Here is "the point." You are winning. You are winning your independence, which you have made huge strides in establishing. Keep living your life as you decide, but I wouldn't go burning any bridges. Why should you . . . it's not necessary. You never know what the future will bring. Your parents are a couple, but you have a right to have a relationship with each of them that is between the two of you. So if you have a nicer understanding with your father, don't punish him unnecessarily. Like, if you have to maintain a distance from your mom, try to touch base with your dad now and then. (Everyone has cell phones these days, so you can phone him once in a while when he is on his own and not have to talk to your mom too.) Even if you have to make up needing your dad's advice on something, like what auto tires does he recommend. Any little thing. He'll feel good to hear from you and for you to value his input. Avoid putting him in the middle of you and your mom. He has to live with her, you don't.

They say you teach people how to treat you. I think you are teaching your mom. She's not a willing learner, so it will be a slow process. Hope you have the patience.
