My ex is dating a new girlfriend, and I don't want to be friends with them.
But you got along well before you broke up. Why don't you want to be friends with them now?
My ex put me through a lot and I don't like her as a result. She acts like a whore.
You should not be so closed minded since the relationship is clearly over. Your ex girlfriend may make a better friend and if you are not open minded you could be losing out on a good friendship.
For real? She even exposed my password because hers was so much better than mine. Now I have to change mine before my family and I get hacked.
It makes things different that she actively did something to hurt you. You don't need to be friends with someone who exposes your private information. It's probably better for you not to be.
