I have seen my MIL twice since my husband and I have been together (2 years and a half) My DH and her have a rocky relationship, they don't really talk because she chose to be a part of BM's life. My DH has a 3 year old son with BM, they were never in a relationship, she was a girl that he met and slept with and when he found out she was pregnant, he wanted to be there for his child. His mom got involved since it was her first grand child and somehow became BFF's with BM. BM's child from a previous marriage who is 8 years old, even calls MIL grandma and they hang out all the time. My husband has told her before that if she wants to see her grandson and be a part of his life then she needs to stop hanging out with his BM and be involved in her son's life. She has refused. MIL and I do not have a relationship at all, she wasn't at our wedding celebration, she didn't send a congrats over, and now she knows I'm pregnant, but hasn't attempted to reach out.
I would like our child do know both sets of grandparents but as things are looking right now, my mom will be the only grandma. And I have a feeling she might attempt to reach out once our baby is born, but how am I supposed to just let her in our lives when she has made no previous attempt whatsoever? Any advice on how to handle?
