She may have self esteem issues. She could be codependent.
My stepmother did these sorts of things in the beginning, but she was still in her twenties at that time. I didn’t understand then (being just a kid ofc) but I’ve forgiven her now. And to her credit she’s mellowed quite a bit as well. But this peace was many many years in the making. I think you both should seek couple’s therapy to raise and discuss both of your issues in a safe loving space, and it may become clear during those sessions that she needs to also have individual therapy.
If she balks at couple’s therapy, then THAT is a red flag.
You can’t please everyone, so pick the audience you want to write to. If you don’t care what angry white guys think, then create your characters however you like.
