Ugh BM being a trouble maker
When BM moved out of the family home (which is now our family home) she took everything she wanted but left plenty behind too. When I moved in two years ago I started replacing stuff and redecorating here and there. I hated the color of the kitchen but left it alone for a year bc my older step son acted like he was going to have a meltdown if I changed too much at once so it's been a gradual process. DH gave me full authority from day one to get rid of and change anything I want whenever I want and his POV was "the kids can have a say when they start paying the mortgage" so it was my decision alone to go slow so as to not upset the kids.
So with that being said, our current playroom used to be my younger SS's bedroom until he was 5. There's still baby nursery decor all over the room and a bunch of baby stuff in the closet. I put it all up for sale on a FB buy and sale page for our community over the weekend (step sons were not here). Yesterday my younger SS came home from school acting like a rude little turd to me. Right off the bat he said "I didn't want you to get rid of my baby stuff." Obviously BM must be part of the same FB group and saw the postings I made. She hasn't lived in this house in four years, you would think that's plenty of time to ask for anything back that's sentimental to her. And if she saw the items on FB and wanted them why not just ask me instead of making comments about it to SS? I don't see any possible way SS could know about the baby stuff and be upset about without BM telling him and spinning it in a way to make him think he should be mad at me.
