<human>: For 10 months, I was dating a guy (never a committed, boyfriend/girlfriend thing) before I essentially broke it off. I got tired of being ignored, putting all the work in, and pretty much getting nothing back from him. It even went as far as he'd call me at 3am with some big problem, I'd talk to him for 6 hours about it, fix it, and whenever I had a problem needing to talk I'd get "I'm not your boyfriend, I don't need to do that". That's basic give and take in any friendship, right?

After I broke it off, I pushed our relationship down to the barely-friends-because-we-hang-out-with-the-same-people kind. I didn't want to deal with his pulling anymore. In the meantime, I met and got into a committed relationship with a guy who fits me in a way no one ever has been able to, friend or otherwise.

We started talking, as both of us were trying to clear the bad air so I stopped feeling the absolute need to punch him around friends when he was being a dick towards me and he stopped with the little digs that he kept sending my way. As we were talking, he made comments like "if you would give me a chance, I want to work on us this time" (He knows I'm with someone else). He also blamed me for not trying hard enough and staying with it long enough (When he gave nothing to  help out the entire time) and then tried to say that he gave me multiple opportunities to know the "real" him through well placed hints (I've told him since the beginning I'm dense as fuck, and will never get them) and I never tried.

I don't know what to make of this, can someone please explain his motives to me?

Can you condense the text into three sentences or less?
