<human>: 7 weeks ago, my boyfriend [19/m]of 11 months dumped me. I was so devastated and cried every day for a very long time. A few nights ago, I got a call from his number but it ended up being a prank call (from one of those stupid sites, where you put in a number and it calls from it... so mature) I thought it was actually him so I texted him saying "mature.." and then.. I looked at his stupid twitter.

He started talking to this girl I hate, and made him stop talking to during our relationship because she was talking shit about me and my relationship with him, and whats worse, he was still talking to her and he used to like her. They're talking again, now after we broke up, and I feel so betrayed and awful about it even though we're done. 

He was so sweet and perfect to me during our relationship, but then he dumped me and suddenly I have the value of a piece of trash on the road to him. I can't understand how someone who used to be so head over heels in love with me, and I was head over heels in love with as well, could do this to me. I feel so down. And pathetic, hence why I made this throwaway. 

I want to just get over him and hate him but I can't  hate him after our wonderful relationship. I still feel so caught up in him, but he is basically.. evil to me. Someone knock some sense into me so I can realize finally that I'm so much better off without this douche.

Can you provide a brief rundown of the text in within 3 sentences?
