How to make your ex realize what he lost.
So I was with a guy for 6 months , my whole family loved him , his whole family loved me.. however in the beginning it was so good we did everything together he was like my best friend. It went sour he became a different person over night he became a very mean person. He didn't want to do anything that I wanted to do he wouldn't even compromise etc. and when he did drive me to work he ed and complianed about he was involved in legal activity witch I knew about and still stuck by him we went to mexico together not to long ago and when we got back he came to my house droped of my stuff with no warning and didn't contact me for a month, then he finally does contact me and refer to me as a booty call, and saying some rude stuff , the I told him to F off! The next day he messages me saying he is sorry and wants to talk so I agreed. Then he makes excuses why he can't talk to me , he is embarrassed etc. plus when we were in mexico he told everyone on the resort he was going to marry me so everyone was congratulating me and when I asked him about he said no he wouldn't marry someone like me.
He has said he is going to aa meetings because of me and he wants to get himself better however Im not sure I believe him, then he tells me he wants to be friends how can you be friends with no contact
I am so confused and I don't know what to think or feel anymore
Does anyone have answers as to what happened and why I am struggling to have some sort of closure and why he would do that to me ?
