i want my girlfriend to love me forever.

Don't we all?  Unfortunately, in my local paper yesterday I read that
scientists have discovered that that wonderful prickly feeling comes
from some stuff in the brain that begins to disappear after about 12
months.  After that, you have to work at keeping her love  - and maybe
yours.
Mark Twain (Samuel Clemens) wrote a little letter to his wife each
morning.  Not a bad idea, but not a practice that one can ever forego
once it has been started.

It is my believe that unearned, unconditional love comes only from
your God and your dog. You cannot make someone love you. You can,
however, try to make yourself as worthy as possible of being loved,
and see what happens.

Auggh. Instead of "It is my believe," in my comment above, please read
"It is my belief."

What if you get tired of her? Do you still want her to love you
forever? Doesn't seem quite fair ...

Get a pink candle and "charge" it by visualizing you and your
girlfriend in a happy loving embrace. Then say aloud:

   "We will always love each other.  
   May the Goddess and God grant this for the good of all"

If problems arise in your relationship:

Place the "charged" candle on a stand on a Friday night during a waxing moon.  
Dip your index finger in love oil and run your oiled finger from the
center of the candle to the wick end.  Then from the center of the
candle to the wick end.
Light the candle and let it burn down completely (in a safe place) and go out.

Ta dahhhh ... love will be repaired.

Or try some other spells!

Being an emotional black hole, sucking the life and fun out of every
waking moment until only the Siren song of Endless Night gives
surcease is a start.

Conversely, you might suss that people can and should have several
relationships before they decide to manacle themselves together.

I find girl in internet at my site. It was really hard to make her
love me. But I have understood that there is only one write way -
always be the best for her.

I think there is a truism when it come to matters of the heart: A
person will love you or hate you dependant upon how you make them feel
about themselves.

There is no 'make' in unconditional and true love.  The most important
factor to conquer is jealously.  Ironically, you may destroy this love
yourself through your own jealous thoughts and fears.  Beware of the
power of your imagination.  Learn to trust one another through strong
communication.  Appreciate that you are individuals with individual
minds and individual lives.  Realize that the intense feelings you may
have now do in fact trail off over time as your brain chemistry adapts
to the relationship.
above all:
Trust and Respect.

I must be high-maintenance, since my God doesn't give me a lot of
feedback, it takes two small lapdogs to keep me happy.  :-)

(reference to Pink's comment, above)

Not remotely possible - forget the girl and get a friendly cactus plant.

By Belief is straight. God is great, you have been created for
someone, my suggestion is to find that someone for you, who loves you.
Because that is even a bigger question for you that who loves you,
instead of a lesser question like 'Whom do i love?'. Be with the one
who loves you and not vice-versa. Go and Just find her. Make this your
life's motto or new year resolution or whatever.

And if you think that you don't believe me and want to marry the girl
whom you like then try some girl who looks like Pamela Andersson!

But, this depends on entirely the person whom you really are... Isn't it?

Love comes from love, so u keep loving her and it will ensure she also
stays in love with you.
A girl loves someone, who gives her freedom, but has the ability to rule her.

Ultimately, a girl who will love you and only you is the one who has a
chemical connection of some kind with you that enables that love to
occur.  You have to make two halves a whole, like two pieces of a
puzzle joined down the middle.  A lot of needs need to be met.

Then, this euphoria fades with time as the two entities either a.)
begin to change in shape along the adjoining border and possibly
dissolve at the border into two separate entities again (which will
happen quickly if the love is not "meant to be".  A lot of external
factors usually is responsible for this phenomenon.  People, let me
know if you want me to write the book.), or b.) naturally become
desensitized and tolerant as the body does to all foreign objects it
ingests.  It is a survival mechanism, unfortunately in the
experiencing of good things in life.  It is a great trait though, as
our immune systems fight against disease, and our defense against
possible pollutants all around us gets stronger with exposure to it.

If the love is true (1 + 1= 1) and you do the following things to
nurture your woman, then she will love you and only you.

1. Compliment her.  I'm not kidding.  Every woman needs validation. 
This is a positive way to communicate with your woman.  Say something
good and you will see good things in your woman.  She will blossom and
create and grow into something quite magnificent.  If you choose to
take what woman can give to you and not offer any kind of gratitude in
return, your woman will find fault in herself.  The gratitude you show
does not have to be materialistic.  A lot can be accompished in a few
kind words a day.  Let the the compliments and material thngs you give
to your woman come from your heart.  Think positively.

EXAMPLE: Sylvia, your body looks wonderful in that dress (even if it
doesn't quite measure up to model stature, you always can argue that
"beauty is in the eye of the beholder".

I like your hair that way.

Complimenting how a woman looks physically is the main point here, but
encouragement in other areas such as her intellect, her housekeeping
abilities, her lovemaking abilities, her mothering abilities are also
extremely important.

REMEMBER: You woman needs validation because it is necesary for her to
blossom and grow as a person.

In doing this, you will meet the MOST important need.  And remember to
be as genuine as possible.

2. Feed the need.  What are her nutritional and recreational needs? 
If you can a.) keep her fed (so she doesn't die of starvation) and b.)
be a little fun, too, then you have also done a great deed to the
relationship.  These needs are the building blocks of the adjoining
border of fusing into one entity. Ask yourself, do we have the same
needs?  This is important, because if it is not, the love is not meant
to be.

So it is now time to assess you and your partner's needs, and where do they stand.

3. Work for it.  Show your woman that you are strong enough to endure
life and do what you have to do for the good of the family.

So get a job if you don't have one, and if you don't like where you
are now, aim higher.

There are more good tips, I am sure, but these three are the essentials.

1. Compliment her.
2. Feed the need.
3. Work for it.

Thank you.  Have a nice day

Just remember... don't be the only one working to keep the love alive.
A lot of girls nowadays only know how to take and take from a
relationship without giving back in return, because they only think
"if he doesn't give, he doesn't love me", but they never ask
themselves if they have put in the same amount of effort into the
relationship.

I'm not telling you to ignore googagoo-ga's advice though, but keep an
eye out to see if she is also actively working to keep the flames
burning. If you want the love to last forever, both parties have to
work at it.

Yes, there are some bloodsucking women everywhere, so watch out.

Like I said, do it from the heart, and if she can't take it, then she
ain't meant to be.

Please keep the advertising out of this.

This is a dignified website.

Except I read the rambling from my first post.  Here is a brief summary:

1. Compliment Her.
2. Feed the need.
3. Work 4 It.

Picture your relationship with your partner as a yinyang sort of
thing, except the middle is not divided, it flows together.  Many
factors affect this flow.

In true love, external factors can be no obstacle to this bond. <---
Healthy relationships can function if they have control over their
environmental factors (everyone else outside the relationship), and it
doesn't necessarily have to be true love.

Well I think that you need to just let her know these things:

1: you would do anything for her just to make her happy
2: let her know no one else makes you happier than her
3: tell her you want the best for her and that you think you can do that!

there you go!
