omg, I know you won't believe me but I do know how you feel, we can go crazy and do crazy things when we are in love - those who were not in love just won't get it, so please don't judge yourself for calls or texts.
It is shocking for you that he could do this to you after what you had, but you know. . My bf that I have been for 4 years dumped me on the phone, after the rehab he had to go to, we were planning to get married and have kids etc, but one day he just decided he doesn't love me anymore and it was all mistakes and that I need to move on with my own life. And you know what he moved and very quick, I wanted to be friends and keep in touch - but he was ignoring me completely, I was texting him for 5 months after he dumped me and I was ignored by him. The he did answer but i could feel that he doesn't give a damn about me.
So don't be surprised, men are different, he is an asshole and you need to forget about him. I know you feel grief and pain in your chest and you dream about him and sometimes maybe you even feel like dying but don't allow yourself to go through all this, keep telling yourself "he doesn't give a damn about me, so I can't allow myself to spend another minute suffering because of him, thinking about him, he DOES NOT CARE". He could have understand your feelings and forgive you, because you had reasons to overeat, but he didn't, because he doesn't need it, he doesn't care, you don't mean for him as much as he means for you.
