<human>: I'm going to make this sound as short as possible, and I need guys perspectives on this, because I know what the girls think. 

I date my ex-boyfriend [25] for 15 months, and I broke things off because of a lot of miscommunications that happened. But during our relationship, in the beginning year, we almost fought none because that's how good we were together (yes, i was stupid to break up with him).  After our break-up, I asked for him back a few times, but because of his bitter feelings, he kept saying no, but I could tell he didn't want to say no. 

After a few months, I got over it and decided that he must have been right about us not getting back together. After about 8 months, I find out from my sister (they got pretty close during our relationship) & his best friend that he still likes me. Here's the confusing thing, he says he still likes me, but he doesn't want to have a relationship with me, so he's looking for rebound girls. His best friend called BS and said that he's still bitter, and he's hating the fact that he still likes me, because he wants to somehow get back at me for breaking up with him. 

WHY I'M CONFUSED : why in the world would you tell my sister that he still likes me, because lets be real, he knows my sister is my best friend so she's going to tell me.. so through word of mouth, he knows i'm going to find out he still likes me. ALSO, how are you going to like someone, but want a rebound? 

THIS IS REALLY TO THE GUYS: what the hell is going through his head right now.

Can you summarize the given text in a few sentences?
<bot>: I broke up with ex-boyfriend [25], regretted it and asked for him back multiple times, but he rejected me [F/23].
