Mother will disown me?

I’ve been through a lot with my kids father, from him cheating, lying, etc for years now. For the first time, he expressed his self to me and told me how he’s been dealing with a lot mentally and that he wants us as a family, he regret everything he has done, and he loves me. Before he told me this, he was talking to another woman but told me he was trying to fill a void from me leaving him, so he left her because I’m who he wanted to be with. I’m no fool, I didn’t let my guard down. I do love him though and I want it to work out for us. I’ve been praying that he become a changed man for his family. I’ve told my mother everything because I needed someone to talk to. I also told her he wants to be back together and she told me if I was to go back to him she wasn’t going to have anything to do with me. Now I’m stuck, I just don’t know.

Edit: I understand where you all are coming from. I’m confused because my mom’s husband cheated on her multiple times and I didn’t disown her, I was there. Now everything in their marriage is better. Even before my mom got married to my stepfather, my real father cheated and beat on her multiple times before she left, my grandmother never disowned her. My sister’s children father did her wrong multiple times, my mom never disowned her. Why me?
