My boyfriend and I were together for over 2 1/2 years, but only actually in the same state for the first half of the relationship since he joined the Marines. Well, he was discharged for medical reasons and is now living in New Jersey (I'm in Michigan) with a friend because his family is crazy and he doesn't think he can deal with them. I thought everything was going great because we were talking all the time and laughing together just as much as ever, but then one day he calls me and tells me he kissed another girl. He feels terrible about it, tells me it doesn't mean anything, promises to never do it again because he was just confused and doesn't know why he did it. We talk and I end up forgiving him because we haven't seen each other in several months, he told me about it, and it wasn't like he slept with her. The next month he calls me up sounding like he lost his best friend and tells me that he must be out to do himself in because he kissed another girl and doesn't know why because he claims to still love me. We "separate" with the idea for him to get his life in order because it really is a confusing time for him because he's only 20, doesn't have a permanent place to live, can't afford to go to school, just got a job so that, he says, he can afford to come back and live in Michigan, and he doesn't really know where he's going in life. That was about two months ago and for the past couple weeks, we've been talking and I thought working things out. He knew that he was going to have to earn my trust back and I knew that I was going to have to be patient and get over the fact that I couldn't see him in person yet. Well, today he calls me up and tells me that he has been seeing another girl for the past week and didn't tell me because he can't stand calling me anymore because I don't trust him and remind him of how he screws up all the time. Needless to say, this comes as a shock to me (even though, I know, it shouldn't) and in the middle of his claiming he doesn't know what he's doing, I ask him how it works that he can claim to love me and yet refuse to stop seeing this other girl. He wants to keep talking to me and tells me he still loves me and to please just understand. What I understand is that I don't think he truly loves me anymore because how can he if he is seeing another girl? I still love him (though, obviously, I don't like him right now) and that just makes it all the harder for me right now. What should I do? Intellectually, I know that I should just stop talking to him and let him do whatever, ignoring his pleas to the contrary, but I still love him and don't want to just throw away 2 1/2 years on something that may be temporary. I know I sound foolish and that the answer should be simple, but for me, I guess it's not. So, what do I do?
