I've been friends with this girl for just under five years now and it's really becoming clear to me that she only cares about herself. Her dad died many, many years ago however, she always seems to make it the center of topic whenever something happens which isn't about her.
For example my sisters just died and I'm wondering if she's actually going to come to the funeral, previously she's stated she doesn't go to funerals because it reminds her of her dads one, her dad died some ten years ago and by now she should get over it and stop making everything about herself in my opinion. Just under a year ago she trashed a friends wake and glassed someone all because it reminded her of her dads passing and she was upset, this always happens whenever she has a drink.
Over all I don't want her showing up for that reason but at the same time she was really good friends with my sister as well and should be there. But if she shows up I can see her making everything about her and her dad, it's beginning to get really repetitive and annoying now. Whenever she's in the wrong she will cry about her dead dad and it's becoming really tiring. She doesn't understand that other people have their own problems such as family members passing away, it always has to be about her. Or she does understand but doesn't care.
How do I deal with a friend that makes everything about her and her dead dad that died years ago? Advice needed.
