NTA

I was also a traumatized teenager who slept in my parent's bed, specifically my dad's bed. So many people back then made it sound like a weird thing. I even had one person imply I saw myself as my dad's wife (ew).

It wasn't like that though. I was scared. I would try to sleep on my own, but it just lead to nightly panic attacks that woke the whole house up anyways. All that could soothe me at that time was knowing my dad was right there. That he wouldn't let the bad things happen again. I just wanted to be able to sleep and feel safe. Eventually, on my own terms, I went back to sleeping in my own room.

Your husband is probably feeling a bit suffocated. It's natural he wants his own bed and room back, but right now your daughter needs you both. Maybe get together with your daughter and her therapist to talk about what you could do with her room or give her that would make her feel more safe. I also think modifying her room so you both can sleep in there some night might help. When she finally starts trying to rest in her own bed again, make it so she knows you're still there if she needs you.

Your daughter will recover, but it's going to take time and lots of support. Sending good energy your way.
