I want my ex back, how do I get him back?

and does my ex want me back? About 2 months ago my ex (we were still together) started acting mega weird…at first i overlooked it, then it really started getting to me so i gave him his stuff back and broke up with him…(something i did all the time, probably just wanting attention), anyway, everything was fine, until a few days later, he just quit talking to me altogether…he was supposed to come to my house and he never came…i started panicking and called and texted so many times (like over 100 i’d say) he never answered. i found out from other people that we were broken up…so we didn’t talk for like a month then, he started texting me and i just ignored them…he’d say hey, and i’ve heard you were talking to this guy and all kinds of other stuff that i never responded to (i thought it would be better)…anyway…one day i really wanted to talk to him so i responded to his text and we started talking…i was extremely confused…he acted like we were best friends…he ask about the guy i was talking to, told me he was there for me (i’d been in a crappy mood), said how sorry he was about things, kept asking how i was doing, said he was glad i was doing good, and just random things he wanted to know about my current life…we kept this up for about a week and i just couldn’t take it anymore…so about 2 days ago i cussed him out and he hasn’t said anything since. i know it was the wrong thing to do i just couldn’t help it…he’s still keeping my stuff even though i’ve asked repeatidly for it back…he’s also said that all this was so hard on him too, and since we’ve broken up he’s friends with this really skanky girl who will have sex with everybody…i’m so confused…please help me, i desperately want him back.
