Send him a letter, giving him X # of days to get his things out of your house or they will go to the dump. Send it with a request for Proof of Delivery, but not that he has to sign for it.
Block him, go NO CONTACT.
You are WORTH SO MUCH MORE THAN A SELF CENTERED SLEEZE BALL LIKE HIM.
You might try some Al-Anon where you would be sure to make some 'friends' and help yourself in the process. Check out if there are any 'book clubs' (possibly through your local library). Join a gardening club (again some like interests). You get the idea.
As you work on yourself, and your 'insides' change, you will draw to you people with similar insides (great folks).
Please keep posting here and let us know how you are doing as we do care so very much!
Love and hugs,
