Someone who has a girlfriend who yesterday put his arm around me hugged me and asked to go skatin?

Don't you have a Dad? If not here is what mine told me because dads know what guys think. He said that boys will constantly test how far they can go. When they go too far they will laugh it off and do it again till they can go further. They constantly try to touch me and wear down my resistance. Pretend its just fun if I protest. But I constantly tell them "STOP TOUCHING ME GET LOST". The rest of the boys who respect that can hang with me cuz they are cool.
One of them even went through my purse. When I kicked him in the balls the whole cafeteria cheered me because he was wrong. Dad laughed but said I should not go so far lmbo.
Stop getting groped. Declare your limits loud and clear.
