I can’t add much more to what it has been said.
There are possible explanations to why she sees things in the way she does and I don’t see as you have a big responsibility in her feeling as hurt.

What you described were normal problems that can occur in a relationship but unfortunately for specific causes you both didn’t get to go over it.

I don’t think you have to blame you from what you have told here. You made, if so, understandable mistakes and you were only there to bring your worries out along with your support. As any member of the relationship has the right to do.
Unluckily, she lives under a big control of her father and this caused a lot of damage.

I wish you the best and that you find someone who makes you happy.
