I feel so broken

My and my ex bf have been together for 6 years . He broke up with me like almost a month from now I hadn’t seen him since the day he broke up with me . But yesterday I went to get my stuff from his house and we ended up hooking up and he said he loved me and missed me but after we hooked up we talked about stuff but not about us and where we stand at . Until today he asks so what now .. I told him I wanted to be with him and he said tbh idk what i want ! And after awhile of me telling him to let’s work things out that I love him etc he said let’s just be friends . And I kept telling him I wanted to work things out and just be with him , and he ended up saying that He thinks of the times He treated me like shit n He tells him self that I don’t deserve that and him . He says he still loves me but doesn’t want to keep hurting me that he don’t deserve me . I told him we can just start over and all he said was we can’t be together that’s it bye ! Like why would he does this ? Why would he of had sex with me and say he loved me and missed me the night before he said this if he just didn’t want to be with me anymore 😭I really thought after us hooking up again we were going to get back together but he just made me feel used because he had sex with me but just wants to walk away and his the love of my life 💔
