My mother is a mom to everyone in her life - except my brother and I.

My mother is emotionally negligent. She avoids real problems with her children (my brother and I) by being defensive, dismissive or throwing money at them, but she is an absolute mother to her loser, cheating, boyfriend and her victim-mentality friends. I'm in therapy with her at the moment, two sessions in, but I have NO hope though. MMFB :(

EDIT: Thank you for all of your comments. It's been really helpful to realize that I am lucky that therapy is even happening, and that if my mom never changes, it just means things are the same, not worse. And at least I can get some benefits out of talking to a professional. I wish you all the best of luck with your moms!
