Friends, or family for that matter, don't have to accept anything about you. Not sccepting some aspect of a person doesn't make them any less of the person they are to you, or what they mean to you. Sure it would be nice if they did accept, but people don't accept things if they don't like. Just because the truth is hurtful, or horrible, its still the truth.
My family doesn't accept my beliefs, my practice of witchcraft, and my religious path. But guess what, theyer still my family, and they still love me. They don't accept it, but they deal with it. And as Lark put in a wonderful manner, don't discuss it with her, for it may be too much for her to handle at the moment.
