How to get a girl to come out of the closet?
Take her out to movies, or park or for dinner; Another method is to become friend of the family, and slowly talk to her and start dating .
Make sure she knows she is important and if people have a different or negative view of her, they are not worth her time to begin with. Thats not to say it will be easy.
Don't force her into anything . It should be her decision to do this when she is ready . Just be there to support her .
