major bf problems?

I think you should talk to him about it, but don't come on too strong because he might get defensive and then it would lead to an argument and thats the last thing you want. Just say how he was logged in and you saw his mails and everything, tell him your confused about who she is and what is happening. Talk about how you feel about the whole situation, if you dont want to break up with him then you dont have to. All you need to do is figure out the whole story and whether this 'thing' is serious or not. If it isnt, and if he really loves you then he can forget about her and be completely dedicated to you. If you're uncomfortable with talking to him straight up then you could always ask a friend to ask him about it first and see what he says, that way when you talk to him you'll know if hes lying or not. As long as you talk to him and find out the truth you can begin to work it out, everything will be fine I'm sure. Stay strong

find out why he did it, whether it was a matter of you not satisfying him (unlikely, guys don't ask for much) or that he is pathologically incapable of being faithful to 1 woman, or he may have had some irrational thoughts which lead to irrational actions. the fist step is to find out why, then you decide what to do from there. rule of thumb; people aren't to be trusted. pay close attention to his eye movement, heart rate, voice stress, sweat etc when you question him. but try not to let him know that you're watching these things

I have been through something similar, Ofcourse I saw something and it made me angry, it made me very upset, he knew he was in the wrong, we both trusted eachother but that just made me think worse in the long run, You will never trust him fully again, and later you will start to resent, him. I do believe some couples get through it, but its extremely hard, you have to think to yourself "when hes texting someone and I can't see, will i wonder who it is, or when he's e-mailing, will i want to check who it is etc" If you think you will wonder these questions, i can tell you now it won't work. I know you love him, and you want to be with him, but you have to think if you can handle it. On my end it wasn't good, I gave him the benefit of a doubt, and I guess he thought he was extremely sneaky because he thought i trusted him fully again, He made me believe that he was faithful when he was the complete opposite, I found out he'd just changed the girls he was texting into male names, so i wouldn't question it, until i actually read the texts (infront of him), Once you let it slide he will think of better ways to hide things, I'm not saying for sure, but usually they'll do it again. Best of Luck
