EleGirl, I do indeed know this is all possible and have seen it happen with someone (not my relationship).
I have looked at further messages and I am confident that nothing has come of it. I have not used a keylogger but I am a computer person and he is not and I hacked all his accounts so...
Anyway, back on topic: I don't want to spend this thread defending or trying to give reasons why he is not cheating. Sure maybe he is, that's not why I posted. I posted because I talked with a male friend about this and he had done the same thing (with no intention of cheating and did not cheat). I got his perspective about why he was doing it and am interested in hearing others. I know this is not as uncommon as it sounds. I think people are just too embarrassed to admit it.
