my girlfriend was having an affair,and was e mailing her lover.i have
the email addresses she used,but they are now shut,and im wondering
wether i can find what the content of her emails where,and if she has
any other secret email addresses from her home computer.is there any
way of retrieving the deleted hotmail emails,and is there any way of
finding out if she is telling the truth when she says she isnt
emailing him anymore.thankyou

I strongly suggest that you decide whether to trust her (in which case
you will not pry into her personal correspondence) or not trust her
(in which case you will presumably break up with her) based upon her
past history, her apparent sincerety, and your own capacity to
forgive.

The decision of whether or not to give her a second chance can be made
without gross violation of privacy (which, in some cases, would also
be violation of law).

she violated my trust and feelings,so violation of privacy should be up to me.!!!!

It sounds as if you seek revenge. Perhaps it would be best for both of
you to put your relationship on hold for a while.

There is absolutely no way that you can discover the contents of her emails!

Do a quick 'cost benefit' analysis

If you reckon that she is treating you like a jerk
- then walk away
- if you wind yourself up, then you risk enjoying some 'striped sunshine'
  (a phrase I recently heard on the World Service, and relish propogating)

If, on balance, it is probably a 'one off', then treat it as such
- don't probe, the chances are that she 'revealed preference' for you
- stay just as long as you enjoy her company - and reckon it is mutual
- otherwise separate (amicably)
