<human>: Hi, guys. I'll try to keep this brief, but give all the backstory I need to make myself clear.

At the beginning of December, I [19] broke up with my first long term boyfriend [18]. First kiss, first lover, first everything. We dated for almost two years. It was a very toxic relationship, he was selfish and sexist, very immature and very dominant, but I never realized it because I had never experienced anything else. Even sex with him was never anything special. We never "made love." We just had sex.

In February, I met the most wonderful guy on earth. He is everything my first boyfriend wasn't, and I am head over heels madly in love with him. Every time we make love, it is passionate and loving and perfect.

My ex-boyfriend, however, still showed signs of not moving on, and swore he would never find anyone else for him, nor would ever want to.

Today, however, I found out that my ex-boyfriend has been casually hooking  up all summer with a girl we both know, whom he will be attending college with, both as freshmen. I also found out that he blocked me from Facebook, seemingly unprompted.

I thought I had moved on. I have no complaints about my relationship - heck - or even my life. But why does this hurt so much? Is it wrong to wish, even just a little bit, that he still hadn't moved on? I guess I just miss feeling wanted. Even from someone who treated me so awfully. 

Any words of advice, or similar stories?

Can you provide a brief overview of the text?
