Controlling and abusive relationshipsWatch
I am afraid these types of relationships are very common and many of my friends (mostly female ones) have gone through them so this could be very helpful. People tend to blame themselves in situations like these or are made to believe that anyone other than their partner wants to harm them and end up trapped in the relationship. I think by seeing what other people have experienced they could escape an abusive relationship much easier.
So what I suggest basically is a sticky providing all the relevant info about abusive relationships, how to recognize if you or in one or if the people you care about are in one, how to help and support someone in such a situation, provide a link to the Abuse Q&A forum, letting people share their experiences but clearly suggest professional help if they are in an abusive relationship. Finally, I think when you know that other people are going through the same thing you always feel safer because you can see that its not your fault and you are not weird or weak for being in such a situation.
