You do know that you quoted my post and then didn't respond to anything in it, right?

You don't need to give up on yourself. You just need to work on making a plan for yourself that doesn't involve relying on your fiancee for everything. That starts with identifying your challenges, so that you can start brainstorming ways to make them easier.

Your fiancee has no control over you bank account - if your father is on the account, then he has control with you, which means that you need him there to help sort that out. Unless you have a joint account set up with your fiancee, then she can't do anything with your banking besides stand there with you.
