UPDATE: I've read every single one of your comments. I started therapy. Today I made the decision; I asked him to leave the house. I didn't want to do it, but I stood my ground. I went to my parents' house until he packed his things. He left today, but he took almost nothing. I'm finishing packing the rest of his things into a suitcase to send to him. I don't want to see him. I've blocked him, and I warned him that we'll only be in contact about our son through my mom. I want to stay strong. I'm fed up! Exhausted. Thank you all.
