DS is coming upto 12 now and is at the stage where he's developing huge crushes on random girls. Thing is, he doesn't just leave it at a crush, he starts to practically stalk them, posting song lyrics all over their facebook walls, posting love-sick lyrics on his own facebook, engaging in private message telling girls how they're breaking his heart and he won't stop until they see how good he is for them etc. He's been threatened by one boy who took offense to DS developing a mad crush on his girlfriend and not leaving her alone. He's getting a reputation of being a bit of a creep :( he's always been like this though, even when he was 7 he became fixated on a malaysian girl from school and would follow her around, write things about her etc. He becomes obsessed with people. I've tried talking to him but it does no good. Do I just leave him to find out the hard way??
