Random ass hypothetical topic

Have you ever had a friend who has cheated on all of her boyfriends? Had they ever stopped?? Do you reckon it’s because of some unresolved trauma? Do you still talk now?

Also, if this person was your bestfriend would you trust them around your relationship? Eg. She cheats every time she gets drunk.

I don’t even have a boyfriend I just get bored on this app, but I do have a bestfriend who does this and is a good friend but people will tell me not to trust her because she does this ... thoughts?
