Should I be mad?

Ok as you know I am 13, and so is my boyfriend. I really like him, I'm not to the point of "love" with him yet but like I said I really like him. At school there's this teacher who has a daughter who is like 18 or 19 or something and he thinks that she is just soooo hot! At first it didn't bother me cuz I thought well she is way too old for him and he is just playing. but latley it's been getting worse. Everytime he sees her he just stops talking to me or whoever he's talking to and just starts to stare at her. One time he moved me from one side of him to the other so he could be closer to her. And these little things that he does like that is really starting to make me mad. But I feel like it's a stupid reason to get mad at someone. Should I tell him what I think about it or just laugh it off?
today he even tried to go up to her and talk to her. but the bell rang. What should I do?

He's disrespecting you, plain and simple. just tell him it's upsetting you.

Im sorry but what a prick u should tell him if he think shes so hot tell him y dont he marry her. and if he leaves u look wat hes missing out on. He probably wont get her anyway. and its ok to be mad because he is hurting you if my bf was doing that i would be furious.

Peace out

Do the same to him, then ask him how he feels now? He'll sure be sorry xxx alex xxx
