Why is he saying so many diff. things?

so my ex fiance and i broke up a month ago on saturday. i am finally moving out of our house this weekend. i asked him to sell my ring before i moved so we can split the money and have no contact after i move. he still has not touche the ring or attempted to sell it. any ideas why? i asked him and he said he would. but hasnt. he texts me and says he is going to be sad and loose it when i move out and he wishes things were diff. and he is sad. he says he has never loved anyone like he loved me. but then he turns around and says i did nothing for him in the 3 years, that i gave nothing up for our relationship, that i was controlling and jealous, and that our relationship was not normal. wtf. i gave up family and friends, my house to move in with him. if our relationship was not normal why did he want me back after breaking up last september for two months. i had a boyfriend when he got me back. i gave that up for him. we were getting married, had 5 kids, 2 cars, a house, 2 incomes, a good life. yes we argued once in awhile but who doesnt. if it was not normal why did he want me back, why ask for my hand in marriage, why were we planning on me having surgery to have a reversal tubal to have another kid? why is he saying so many diff things? he is so up and down lately. i told him we should try to make things work he said he cant and wont cuz nothing has change. and he said he cant and wont make promises for the future. seriously. whats up with my ex fiance. i know he is not with anyone else. he is not even that kind of guy. i am positive about that. why is he not selling my ring like he said he would? why is he saying so many diff things? i am so confused by his comments and actions. he tells me to my face with tears in his eyes that he doesnt love me anymore. hello thats not normal. help lol
