Great woman, great relationship

I'm in contact with a good woman for 6 months now and I felt uncomfortable the past two weeks.

I met her father the 3rd time when I brought her home, he was drunk and threatened me and my family indirectly. He cried, I hugged him as he just wanted to tell me to treat his daughter right.

Then I got to know that her famiy and her always gather with drinks, "moderately".

Once she was out of character and told me that I shouldn't tell her what to say/ or not say/do. Triggered her with "don't do that" when she once repeatedly made vomit sounds out of a statement to how certain animals are killed.

Well, yesterday I opened up my concerns amd that I don't feel comfortable anymore.

She's in love and of course switched 180° like nah I didn't mean it that way, I would do everything for you and that alcohol is not that important to her.

I feel at ease but I am at the edge of letting go and staying. I imagined myself in the future, and I don't know if I would be happy surrounded by people who can't have fun without liquor (Her family side) + the incident with her dad.

Do you have advice?
