hrm, Sometmes we have to bust their bubbles and tell them how we feel. We can only take so much for so long...so, you've said what is on your mind, now step back and allow God to have him.
Mlcers will threaten to leave or do something to get us to back off and leave them alone. They can't handle the up close and personal aspects of our feelings/emotions or us wanting them to do something.
As for counseling, time will tell if he will go and if he goes, just how long he will continue w/it.
Right now, he's going to be Mr. Goody Two Shoes become mom was angry. He'll get back into the mlc mode again very soon.
Please take care of yourself. I know it's tough having them live in the home. Stay safe during this storm.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
