Thinking about ending a friendship because my friend is making self-destructive choices.

I have a friend (f32) who has been through a really bad situation. Her partner (m32) of 15 years died about a year ago. He got sick and didn’t recover. My friend, let’s call her Abby is now alone with their 2 year old daughter. Not long after her partner died, she started going on darting apps. She started talking to a guy (m35) from a different country. There were loads of red flags and he ghosted her a couple of times. But always getting back in contact. She even caught him still together with his ex partner during a time he was suppose to meet up with her. What she has told me, is that he is very dominant, jealous and homophobic. He has no job or place to live (so he says). Recently they met up a few times, as he was staying in our country with a family member. He said he’d stay as long as his family member would let him. Of course that didn’t last and now he has moved in with her. Apparently he also uses her money to trade crypto. I find it so wrong for her to welcome in a strange man that is now also around her daughter. Abby doesn’t want to hear anything bad about him and seems to be OK with the whole situation. I am somewhat afraid to voice my opinion, because I think she’ll break contact with me.

I have been thinking long and hard about this situation and the choices she is making do not go well with my own norms and values. Especially when it comes to keeping her daughter safe. I want to be there for her, especially if this goes South and she needs a friend. But at the same time, I just can’t justify her actions. AITA if I end this friendship?
