For context of why I was worried: I really wanted to be happy she was engaged, but she tried to unalive herself while i was on the phone with her during one of their arguments and it kind of traumatized me. I tried to get over that, but a year later she had another episode like that where she broke up with him, threw things, disassociated, just to pretend nothing happened and get engaged to him 3 weeks later. It was too quick of a turn around for me not to be really concerned
As someone who has had friends with toxic boyfriends, friend groups, and stuck through thick and thin with them, then cut her and them off- it’s not your responsibility to make sure she is safe in a situation she put herself in. She doesn’t owe you anything and you don’t owe her anything either. If anything id say it’s best to call off the friendship altogether if she’s the one doing it anyways- people with problems don’t want to be told they have problems. It’s up to them to end it all.
