Dear @Lostpossum,
I read your story and am very sorry. You seem to be a very caring and loving partner. What struck me most, was the part about blocking people. I think this is a lot to ask.
The fact that she asked you to block three family members... and at the same time could not stick up for you, when her dad wanted to block you from her live... that sounds like she must have been hurting in many ways, in order to act that way. On this I can't add much.
I wish you all the best!
