I would try to get therapy for your daughter, and for yourself separately, to process & have support for everything you are going through... both as a mother, and a survivor.
And try my best to not confront him again while having him far from my family and daughter...
ur daughter & you are worth your time. He, nah.
I really agree with everything

A lot of the time when someone we love is hurting are first thought is how do I fix this and how can I get revenge. Both can lead us to doing unhelpful but completely understandable things.
Have you thought of asking her what she needs? Because sometimes it's not what we think. We can assume things because of what we have been through but even if it is the same exact trauma (which it's probably not) people need different thangs to get them through.
My dad is not very supportive when it comes to my trauma. Don't get me wrong he loves me and would back me 100% if I was really in trouble. He just has literally told me I'm not allowed to talk about my trauma with or around him. He tells me if I'm having a bad day that others have it worse and it's not a big deal just get over it it happened when you were 6 just forget it and so on.
My dream would be for my dad to just sit with me. Say I'm sorry I don't completely understand what you are going through and I know I can't make the hurt go away. I just need to know one thing what can I do to make today a little bit better.
And keep asking keep saying things like if you need to talk I'm here to listen. I love you what do you need from me right now.
In your case it may be nice to say something like. I have PTSD to I understand on some level what your going through every though are storys are different and I can never fully understand. if you ever want to hear my story I will tell you. I just want you to know your not alone.
Also do things that don't have to do with this. Send funny memes, go to a coffee shop and talk about how cute dogs are or whatever is not triggering.
Just be there for her never let her doubt for a minute you love her. This won't go away quickly understand that this is probably something that will take time it's not a one time thing. It's continueing to be there.
Sorry this is so long there is honestly more I could say but this is a good start in my mind.
Also make sure you are talking care of your self. Both you being in therapy is a great start. Also try and find people you trust to go to when your having a bad day.
I hope this is a little helpful. It's just what I would have wanted but really the key message is ask her what she needs and do that.
