<human>: Can you succinctly summarize the text in 1-3 sentences?

My ex of 4.5 years went on a "break" with me 2 months ago and texted me/called me pretty frequently up until 1.5 weeks ago.  It was an agonizing decision to him to go on a break with me but he still did it; I was obviously devastated and always answered his calls/texts even though it never meant we were going to get back together.  He would call me crying and telling me he loved me and wanted to see me but just couldn't get back together with me.  We had a great 4.5 year relationship but he always had doubts about me and could never commit and that's why we went on a break.

He hasn't contacted me in 1.5 weeks.  I look on facebook, and he is clearly starting to get into someone with some (very pretty) looking girl.  I am just devastated.  I knew he was sorta using me to feel better and now the truth is, he has dropped me since he met this new girl.  I called him like 10 times tonight and he didn't answer.  This pain now is so much worse than when we first broke up.  It's like, real now, he has found someone else to share everything with (so it seems).  His dog, his new apartment, everything.  I can't stop thinking about it and crying nonstop.  I was wondering why he stopped calling me, and now I have the reason.  Please someone tell me something to make me feel better.
