Rose, you did the right thing to call the police, your son doesn't listen to you so maybe he'll listen to them.
And I am sorry that he continues to show such disrespect for you. Maybe it's time to just let go and let him live in his own dysfunctional world for a while. You can't change him, Rose, anymore than I could change my son. It's up to them to find help when they are ready.
You deserve a better life, Rose, and my thoughts are that if you let go you will be able to enjoy your life so much more. We are entitled to do that, you know, to live our lives well and find some beauty in every day.
Sending big hugs because we've walked this road together for a long time now and I know how rough it can get at times.
Hugs
