I know I am the only one saying this and that it's not a popular opinion. I find it morally repugnant that his wife had the nerve and the balls to ask him to parent a child that was conceived by cheating. She cheats and there are no repercussions for her infidelity and breach of trust. I highly doubt she slept with her lover just once. Pretty uncanny to get pregnant on the very first and supposedly ONLY try. And who is to say she won't cheat again with this man, or with some other man? Sure, he can adopt if the bio father agrees. Sure, they can maybe be happy, if the husband forgives the infidelity. It's a very tough position to be in. If it were me in those shoes, I'd say hell no to her and I would walk away for good. But that's just me, it's not my life and it's completely up to the OP. No need for anyone to respond to this.
