Sorry for the long post but I've been here a while and I need some serious help now. My sister is a slut. In other areas she is confident, she gets good grades, and she looks like a model teenager (She's 18 and in grade 12). It's also only when she gets drunk. It's sad because she knows that guys take advantage of her when she's drunk and yet she still does it. Before she goes out she knows that she will get drunk and do something stupid. She says all she wants is a boyfriend when she's sober and she's very pretty, so I don't see why she couldn't have one. She's pretty emotionally stable for a girl. It's a smaller town so she has a very limited number of people to pick from though. This has been going on since she was 16 and I want to know how to approach her without blowing up. None of the other 3 kids in our family are like this, despite all of us raised the same way. My first instinct is too find the guys that sleep with her when she's drunk and they are sober and kill them and my dad only knows part of it. He could easily make them disappear so I refrain from telling him everything (And he really will because regardless of the moral actions of the guys, my dad will consider this rape). My mom knows all of it and she has tried talking with her and put her on birth control but what can my mom do when my sister sleeps with losers that fuck anything that moves without condoms? The 19-20 year olds that didn't go anywhere after high school and still try to get with high school girls and who all the girls like. You know the kind. Not only is it emotionally unhealthy but she could get STD's as well. It's affecting our whole family and we blow up at each other over this all the time because we are so stressed. My plan is to sit her down and calmly tell her how it makes me feel. How it makes our mom and her siblings feel. That I love her but right now I don't respect her and if she wants to change that that it will have to be through her actions, not her words as her promises mean little right now. She is coming to one of the best universities in her field in the fall and moving in with me (I live in a nearby city). I want to try and change her actions before she moves in because that kind of behaviour is not going to fly in my house. Yelling and telling her to smarten up and get her shit together or threatening to kick her out has pushed her further as you can imagine. So if you've read this far please offer any advice you have.
