Ex said he hates me, now he wants me back?

[Danielle]

Me and my ex are both 18 and we were together for 1 and a half years. We broke up because of other people getting involved. We broke up just over a month ago and he's been giving me mixed signals ever since and just two days ago he told me he still loves me and always will. Then yesterday, he told me he doesn't love me and that he never has. He's told me to go die and that I'm just dirt on the ground. He now says he can't stand me and he talks to girls I hate and I know it's just to get at me. I can't eat and I haven't been able to concentrate on college work recently, so after last night I just decided not to speak to him and deleted his number, blocked his twitter and he already saved the trouble of me blocking him on facebook as he did that a week ago. BUT he's texting me already saying he wants me back!? (I recognise his number) He's been so horrible to me but now that I decide to ignore him he starts saying this!? WHAT is going on!
