Of course she was happy. She sees this as a win. Even if he does foist her off on his parents, you taking yourself out of the equation still sends the message that you’re not going to enable his bs anymore. Have you talked with his parents about this? These are your prospective inlaws. I’m sure princess is painting mean ol’ lezlers in a not very nice light to them. Take your future mom in law to lunch, feel her out about it. Tell her you don’t want to come between him and his daughter, but you feel like maybe he’s using you (both) to avoid dealing with his daughter. Which he obviously is.
Well…she’s wanting for her father’s love. She thinks. He loves her, he’s just clueless about how to deal with her. And when she has real trouble in about 6 years, he’s going to wonder why she’s having so much trouble. He isn’t doing either of them any good.
I feel for you; the situation sucks.
