I have this one guy friend whose been my friend for ages and he can be a good friend at most times. Although lately he hasn't been treating me very good. During the summer the two of us always went swimming together, but he would drown me in the 10 FT! And at first it was ok because I thought it was cute and i'd always seen guys pull girls down under the water a couple feet in the movies and stuff if they liked the girl. So I let it slide, but he kept on drowning me and I would be down there for longer and longer each time. Eventually I would be scared that I would never come back up. Also he started pinning me to the ground. And while pinning me, he would put his one arm around my neck so i couldn't move or get away because I'm not strong enough. I asked him to stop and he did. But now his one friend just came back from pakistan a couple of weeks ago. And the friend who just came back is only 13 years old. My friend and the guy who came back from pakistan started asking sex questions like would i do it with the 13 year old kid or if he was my age would I do it. And when I say no they won't take it for an answer so i have to god promise that I would. and its very embarrassing. I don't want to have to de-friend him anymore but I think I should, but I still know he can be a good friend. what should I do? Thank you.
