My husbands awful mother

I’ve already posted about her with a very long story so I don’t want to bore any of you ladies again. Everyone did agree with me. Long and short of it my husbands mother is a complete miserable, vindictive person. She owes us an apology for something horrible she did. Then two weeks ago I found out from my father in law she lied and she is single handedly the reason for his family tearing apart. My husband apologized just to keep the peace and she isn’t apologizing. It’s been since April. I never say the word hate because it’s such a crappy word but I truly believe I hate this woman. I wouldn’t care if she was ever in my life again, but believe she should be in her sons life and try every single day. I’m a mother and I would NEVER go months without talking to my child ESPECIALLY If it was my fault. I’ve tried everything to get my husband to reach out to her, but he reached out once and hasn’t gotten any reciprocation. He’s done being the “bigger person”

Anyhow, we are trying to get pregnant and before the blow out, his family has known. So my question is, do you think it’s wrong that I will absolutely refuse to let her in our lives if and hopefully when I get pregnant? I don’t believe just because I’m pregnant I should just push aside the fact this woman owes us an apology.. I mean she really should beg for our forgiveness, but I wouldn’t go that far. I just want an apology. A real one.

Side note: I haven’t talked to my parents in 22 years and I don’t want this to happen with my husband and his mother... but I’m also not going to let this tear us apart. I am lucky because he chooses me and my daughter over his mother.. because she is making him make a choice.
