I have been with my boyfriend for a little over a year, and we live together. I always knew he was flirtatious but never really thought anything of it. The last couple of months, though, things have been a bit weird — we've been fighting a lot and I felt like he was being secretive and hiding things from me. When I started to snoop [1], I found out that he had been emailing and messaging all sorts of different girls, sexually and completely inappropriately, on MySpace, Facebook, AIM, etc. I confronted him and he gave me a list of excuses: that he doesn't find me mentally stimulating so he goes outside of the relationship (online) for a quick fix, that he feels like our connection isn't there as much as it used to be, and that he thinks he has an online sex addiction.
His addiction claim sort of makes sense to me because he seems overly sex-crazed when it comes to looking at women online, but what makes me doubt it is that he only seeks out these women when we are in a fight! If it was truly a sex addiction, wouldn't he be doing it 24/7? If in fact it is a sex addiction, do I stay with him and try to work on this together or should I just leave the whole situation now before things get worse? I love him with all my heart but I don't know what to do. Please help!
