It sounds to me like he obviously *does* want to be with her, but has taken the wrong advice from this thread.
I'm just pointing out a pertinant aspect that was raised that seems to have been completely ignored.
Most people here advised him not to take her back, *because* she stopped having sex with him before she ended the relationship, and I'm saying that it sounds like she had a good reason for putting a hiatus on the sex.
and given that she is what, 22? and has been with him for 4 years, it sounds liek she was wondering what sex with someone else might be like, if she was missing out of something because he was being selfish in the sack, so she slept with someone else *after* they broke up, *and* she was drunk, so it is understandable.
So, now, it seems like she doesn't want to lose the emotional connection they had and wants to try to make the relatiosnhip right, and from the sounds of it, the sex just has to be worked on, they don't have any other problems.
I mean, I was reading all the advice you guys were giving him when i was probo-banned and was frustrated i couldn't say this to the guy before he broke up with her.
I didn't say anything more afterwrads because it seemed a done deal, it was over, but he keeps bringing her up, he seems miserable, and I think he owes to to himself, and to her, to meet up and talk about what exactly went wrong, because if it is just the actual sex, then that is totally solvable, it's not like she was out cheating on him or something and can't be trusted. Which is the general sense I got that people were trying to make her out as, as someone who would eventually leave him and break his heart, when that might not be the case at all. I see no evidence that has been raised to suggest that anyway.
