He has told me today. There are loads of things he wants to do with his life. I am holding him back apparently. I have mobility issues. I asked if there's anything I can do to make him stay. Even begged him. I love him so much. We have so much history together and he's throwing it away. Kids are grown with their own lives and just when we can start living ours he has thrown it away. We have had problems in the past with his infidelity ( 18+ years ago) and I gave him another chance. Everything seemed to be ok. Now this has happened. I guess I'm asking AIBU to think I can change his mind or even should I try? He swears there's no one else but he wants to do stuff I can't do without feeling guilty and he can't if we're still together. Please help me make sense of this.
