Self esteem will help a lot with this. A lot of girls I've known who've stayed with men like this do so because they don't think they can do any better! (which is almost always WRONG!) Help her to feel beautiful, smart, and desirable.
Compliments, new hobbies, and excited plans for college or career can go along way in making her feel worthwhile. At the same time, see if you can introduce her to any nice guys. Guys who would probably like her back...and treat her a lot better.
Let her know she has other options. Otherwise, just be there for her when she's down. She's probably going to have to learn this lesson the hard way - on her own.
Good luck!
First, I totally agree with everything Gno said above. The only thing I can add is we need to get her away from this guy. He probably continues to make her feel bad - it simply can't be a healthy relationship.
After that, start from the ground up with her self-esteem and building her confidence back up. Do fun girl things together and make her feel good about herself (although that's kind of up to her). Still surrounding her with people who love her and enjoy being around her will have her back on her feet quickly.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
