<human>: Summarize the given text in a few sentences.

I finally went and told my ex that I'm feeling "over him" and I asked if we could still be friends (he broke up with me). He asked if I had been with anyone yet, I said 'no,' and he said 'that's surprising.' Kind of taking a spiteful tone and not really believing me.

I've been in the process of trying to find out exactly why he broke up with me. The most obvious reason is what he said "to date other people," but I don't know if he wants to just screw other people or find someone else to love (he's dating like a mad man right now).

I THINK the main issue was trust, and I want to know if trust issues can ever be solved. At the very beginning of our relationship I 'cammed' with someone a few times online (I didn't consider it cheating at the time, I know better now). I lied about a lot of stuff, but I realized how wrong I was (young and dumb), and after that we had a solid year of pure truth, full access to my everything, and me being deeply in love with him (made several major sacrifices to show that).

But he ended up leaving me anyways, and now he can't talk to me because it makes HIM feel bad. I don't really get it. He only ever said that he has regrets as well, and that he'll contact me if he ever feels better (which may be never).
<bot>: I still want to be friends with my ex after he dumped me, but he feels bad (I think its guilty) when he's around me. What does it mean?
