SO lived with step grandma in his late teen years, the first time I met her she was very sweet but the couple times after she was very rude and kicked me out of her house multiple times to prove a point to SO about one thing or another that never had anything to do with me. She never had anything nice to say about me, until we told her that we were expecting. She often makes rude comments to me while SO isn’t present, has suggested I’m taking him away and told us the other night that after this child she hopes we don’t have any more. It was a slap in the face considering we thought SO was infertile after chemo and this was a surprise baby we were blessed with. I have a baby shower that she keeps asking about and I don’t know how to approach her about the situation when I’ve given her ample chances to make amends and be respectful and she can’t seem to do that. I’ve gritted my teeth through family parties and made the best out of the situation but she still seems to go out of her way to make a rude comment or try and hurt my feelings. How do I explain to her that she’s not invited, when she doesn’t realize where she’s wrong? Anytime she’s called out or confronted she seems to think it’s out of context.
