Detach from them…live on your own, and spend Very little to no time with them. You can’t change them and while they are certainly not healthy, there is nothing overt that you can charge them with. Placing boundaries means making space away from them and going on with your own life. Nothing they can do, as an adult, can hurt you. You surround yourself with happy, healthy people and limit any time you are with them. If they ask why…tell them the truth. They might get mad, but at least you have your say and can respect yourself. I know you love them but unfortunately, they aren’t treating you with love. Therefore, in the name of self preservation and happiness, feel compassion but make space.
