Wwyd? Ex girlfriend acting ridiculous

Let me preface this by saying my brother avoids confrontation at all costs. He’s sensitive to other peoples emotions, so he does everything he can to avoid upsetting others and it’s not uncommon for people to walk all over him.

My little brother is a junior in HS and he was dating this girl for about a year. We thought she was really sweet, but over time we noticed she would get angry with my brother for seemingly no reason, or because he didn’t want to do something (example, she asked him to go with her and her family on a 4 hour drive each way to a waterpark and to see her extended family for her birthday. They were leaving at 5am. She asked him the night before the trip, after his football game where he sat out the last quarter because of a knee injury. He said no because he was tired and in pain. She told him he didn’t care about her and didn’t talk to him for 5 days.)

Skipping ahead to the issue at hand, we had thanksgiving dinner at my parents house and extended family we don’t see often were there. After dinner we noticed my brother’s girlfriend was mad at him, stopped talking to everyone, and eventually walked home (she lives a few blocks away. My brother asked her multiple times to let her drive her home and she said no. We heard this ourselves.) Her dad called my brother and yelled at him for “forcing” her to leave and to walk home. Why did she get angry and leave? She wanted to sit in his room with him and ignore everyone after dinner but he wanted to talk with our cousins and other family we didn’t see much. After a week of ignoring him again my brother asked me what he should do because he wasn’t happy with her anymore. I told him if I were him, I would break up with her because she was always getting mad at him for no reason, we could see how deflated he became when she was around, and he’s young and doesn’t need to have all this drama from a girlfriend. He tried three times in school to talk to her, but once she realized what was going on she would walk away from him. She wouldn’t spend time with him outside of school. Finally he got her on the phone and told her “I’m sorry but I’m breaking up with you” and she immediately started yelling at him so he hung up. From there she started blowing up his phone so he blocked her.

It’s been two weeks since he broke up with her, and he’s come to me for help multiple times now because this girl is basically acting as if they’re still together. She randomly comes up to him and starts rubbing his shoulders, playing with his hair, touching his arm, hugging him, asks him to call her when he has time, yesterday she kissed his forehead. The first couple times she did this he said he froze up and didn’t say or do anything because he was confused. He’s told her multiple times now that he doesn’t appreciate her touching him and he isn’t her boyfriend anymore. After the encounter yesterday he told me he didn’t know what to do because she wasn’t getting it or just didn’t seem to care and I told him he was going to have to be more firm with it and honestly at this point I’m tired of her bullshit so I told him to be mean if he had to. Today she yelled at him for breaking up with her, called him an asshole, then hugged his arm. I asked him what he did and he told her to keep her hands off of him, he doesn’t want to speak to her and to leave him alone. She laughed and said “yeah sure baby, see you later, call me when you’re free” and rubbed his arm before walking away. He called me between classes and I told him we would talk when he gets out of school. I’m ready to tell him to go to the principal or RO and report her for harassment because he doesn’t need to deal with this shit and at this point it seems like it’s a game for her. If this was your son or brother what would you tell him?

And before anyone can say well he should just avoid her, there’s only so much he can do in a school of 120 kids. They have multiple classes together, they only have 30 kids in the junior class, the school is a rectangle with a gym. There’s no avoiding her if she’s this pushy.
