I know you weren't man, no worries. That's just what popped into my head when I read your post and figured I would jot it down, maybe help you see another point of view of a transguy.
My ex cheated on me because she is a compulsive liar and cheats on every person she is with whether biomale, biofemale, trans, or anything else. She just cheats on everyone. I knew that and stayed with her so long because I loved her so much. When her daughter (Bella) was born, I was there. I held her even before her mother did and my ex thought I was a great parent but she will never change. She just will not stay faithful to one person. I hope one day she will because it would be sad for her and Bella both.
As for the cash, I work part time but I have a lot of bills. It looks like I'll be getting my name change this month hopefully but surgery seems like it'll never happen at the moment. I might end up trying to get loans.
