Dealing with a petty ex girlfriend
I have an ex girlfriend who is mad at the fact I am now dating someone else. However we have mutual friends, we had an incident where she was drinking, tried to get back with me and hit me in anger... I was cordial before that but now I don't speak to her. I want no dealings with her but we share like 12 friends. She does annoying things now like if we are at house, she will put her foot up on a sofa so I can't have the only available seat, and then offer it to somebody else. Goes out of her way to offer food to everybody but me... make smart little side comments, etc.
