Does this make me a bad person?

I've been getting very annoyed with someone who has become my best friend over the past few months. We have so much fun together and we do everything together but there's one little hang up. She is very close to both of her parents in particularly her mother and I think that's great. But she's spoiled rotten and she constantly talks about them. How much they love each other, how close they are, how much time she spends with them, how they worry about her and protrect her, how they are her safe place and how they dote on her. I don't have parents and quite frankly I get sick of hearing about them. I met someone on here who is parentless and we could talk about that common factor together and try to cheer each other up but I don't have that now and I miss it. She relates to me so good and we made each other feel better because both of us have depression about it and it makes for some lonely nights. I haven't been venting to this friend and I'm totally sick of hearing how perfect life is for her and her parents. I have hinted to her in subtle and friendly ways before but she's oblivious and continues to make me feel bad. I talked briefly to one friend today and we got to talk about it so that cheered me up. Am I a bad person for not wanting to hear about her parents?
