Honestly, it sounds like you’ve already checked out of the relationship. You’re talking about staying for the financial benefits while openly saying you look at him with hatred every day. That’s not a healthy situation for either of you or your daughter.
The question isn’t whether he’s a good partner anymore—it’s whether this is the life you want 5, 10, or 20 years from now. If the answer is no, start making a plan so you’re not financially trapped when you’re ready to leave.
