<human>: Can you condense the text into a few key points?

My girlfriend and I have been together for six months, we've been very happy and things seem to be going fairly well except maybe for the past week. She has had a very rough home life her entire life and I've been trying to support her as much as I can. This past week though, her mother, brother and herself very quickly moved out of her home to get away from her very dominant father. He found out as they were moving and tried to gain custody, but she refused to move with him. 

She tells me she is happy to be out of the living situation with her father, but I am having a difficult time wrapping my head around everything. I believe she feels stressed but she won't admit to it. She doesn't seem like herself and I'm finding it very difficult to offer support for  something that hasn't surfaced. I can feel a bit of a tension between us and I think it's taking a toll on us. I'm getting stressed out just thinking about it. I don't really know what I should do to address it if at all.
<bot>: My girlfriend just got out of a bad living situation but I feel like she's still very stressed and it's taking a toll on us.
