he has a group of people that some would call friends but he isn't really shy about how he feels about them. I guess of the people in his "group" he only really likes 2 or 3 of them and dislikes the rest. He isn't an easy person to be friends with because of how generally odd he is. He isn't stable and will switch his opinion of you in a second. He is good at faking though so many of his friends will be fake friends. Probably has like half his friends as other rich kids and the other half as people he could never really justify to his parents. So druggies and other kids who would rather spend time getting drunk then going to school.
like half his "friends" fit in here. He probably has more enemies then anything he just doesn't know when to not tell people off. He has no filter and his inability to really relate to other people makes him selfish. He has probably crashed your party or just gotten way too drunk at your party and broke something so it could genuinely just be a dislike of him for something like that.
lovers is probably the wrong word since he isn't really sure what love is? His parents probably haven't loved each other in 20 years and it's not like even if they did they would be around to prove it. Anyway he has probably slept with 3 or 4 girls I haven't kept track but they were almost all hook up's or fwb type situations. I don't even think he has ever had a girlfriend in the proper sense of the word. He is far from romantic and isn't really sure what that even means. He's too good at picking fights and causing drama for a real relationship, honestly.
Another layer to this is that his parents pretty much demand he dates a girl who they approve of, so while he can sneak behind their back he could never date most of the girls he knows. Basically unless they come from a really good family/have money he probably would be told to cut things off with them. He would mainly need hook up' and fwb's but being in high school makes even this pretty insignificant in his life even if he talk a big game. He has crushes and has quasi-dated people but he really sucks at it and ends up getting in trouble,
so he would probably fail at dating anyone right now.
