Maybe MIL

My BF's mother does not like me. She barely speaks when she see me. She host a girls night out 1 a month and she never invites me. My boyfriend and I have been living together for a year. We have been in a relationship for 3 years. He has been talking a marriage but I do not know. By the way my family opened their arms as soon as they met him. I talked to him about it but nothing has changed. Yes, this cause problems in the relationship. Do not know what to do?
