The good thing about this is now that you are grown up and not living with your mother anymore, you have the right to make decisions about how and when she can or will see you and your children (if she accepts your kids. I wasn't sure from your question if she does or not). My mother-in-law has said many hateful things to me and tried to control us and our decisions as well.
When she behaves out of turn like this, my husband, who is thankfully on my side, not hers, will stand up to her and let her know point-blank that if she wants to be a part of our lives, she will discontinue this behavior immediately. He has no qualms letting her know that we could easily step out of her life and not see her again, and this usually puts her in her place. For your situation, I see 2 separate issues, one of which is DRASTICALLY more important than the other.
It is sad that your mother never accepted your dad's mistress, but I can't say that I blame her for that. The fact that she, out of spite, took it out on you is terrible. But that doesn't even compare to how she treated and continues to treat your wife.
I would recommend that you, before you cut her off, let her know that this is your life, you have chosen it to be this way, and unless she wants to alienate you and estrange you and her grandkids for the rest of her life, then she will have to accept you, your wife and your family. At this point, the ball is in her court, and it also gives her "one last chance" to reform her ways. I don't hold out much hope for someone so twisted to reform, but it will at least give you a peace of mind knowing you did the right thing in giving her this last chance.
Ultimately, you'll have to stick to it, though, because having this much hate in your life is not healthy for anyone involved! Good luck! I am saying a prayer for you!
Aside from your mother being racist, everything else is understandable. Your dad cheated on her, and then she later finds out that her OWN KIDS love the wench that slept with her husband?! Your mother has not only been betrayed by her husband, but by YOU AS WELL.
If I were in her shoes I wouldn't have attended your wedding either. Would stop giving you gifts, and honestly, I would leave first. I would NOT have anything to do with you anymore.
Your mother is the one who should consider leaving. For once, put yourself in her shoes. I'd be ashamed to have you as my son and honestly, you'd be dead to me.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
