I painted my living+dining room with satin paint and primer in one. Why does it peels when something rubs against it and when I put my leather couch against the wall? I pull it back and the paint sticks to my couch, I’m tired of repainting.

Our home is painted Navajo white and windows are trimmed with black. What color should we paint door? Used to be stained. We have a tile roof and pillars on front of house. Home is 20 yrs. old
