Is it wrong?

is it wrong I don't want to be friends with someone anymore because I don't agree with them. My friend has no financial means to support a child or the proper housing, she doesn't even know how to drive and neither of them have a car, but she and he bf were TRYING and now she is pregnant. I feel this is stupid, selfish, and impulsive. She is a very impulsive person anyway and this isn't the only thing she has done I haven't agreed with. I feel bad that it is pushing me away but I can't help how I feel. And it does bother me.
