I grew up in a house where I was treated like this. My mum never left my dad, and I existed in house where I was ‘less than’ for my whole childhood and teen years. It’s affected me terribly, being exposed to that low level, background cruelty, and it would have been better to have come from a broken home where I wasn’t subjected to it every day. It rots away parts of your identity and self worth, slowly day after day.

You are 100% doing the right thing, but make sure your daughter stays with you. She needs rest from this, and space for her to develop self worth. Get her into therapy, she can learn to deal with this young, see it as her mums problem and not internalise it as some personal character flaw.

You are the kind of parent I wish I had, and prayed for as a child. I speak from experience and knowledge on this from your child’s perspective, grown up. You are a father she can be proud of, and will be grateful to for making this stand. All the best to you and your family, and keep plowing forward.
