Is she my Friend or not?

I have a girl friend who is never available until her boyfriend ( 4 years relationship) says he is not meeting her that day. The point is, we cannot make plans to go shopping or salon or anything until she is sure he doesn't want to meet her. I'm married with kids, my friend leaves with a roommate, her boyfriend leaves alone. I'm not sure what's is wrong here, but I believe she should be able to make her plans and follow up with them.
