how to get over my ex boyfriend

So my boyfriend split up with me two days ago but before that he split up with me we sorted thing out spoke to each other and out of the blue he wanted me back the first time he dumped me it was because he didn't want what I want and I was moody and bitchy so we sorted things out got back together things were alright for a couple of days then it went weird he was different. It was a Saturday he asked me to meet him but I was going out and I don't think he liked the fact that I was then he said he didn't know what he wanted then ended things again. That's left me feeling mugged off. Why ask me back out if he didn't want what I wanted? I just don't know what to do now 😔
