I'm sorry you are in this situation. You will receive a ton of great information and help from this site. Keep your head up. Read all of the links that were posted.
Not to worry you but your H may be having an affair. At minimum he is a Walkaway Spouse (WAS)
Post more about his behaviors at home. Are there any red flags? Change of clothing style? Hitting the gym more? New friends? Hiding his phone? Very combative and argumentative when asked about anything? Does he shower more often? Groom differently?
Does he blame you? Rewrite history?
Again keep posting. Give us some background. How old are you both? Any kids?
Keep detaching. This is for your emotional health and safety. No talking about your relationship or the future.
I personally would not move out yet. However, if its unbearable or dangerous to be at home then yes move.
Before you talk about anything with him come post it here for feedback. Any situations arise come post them here for feedback. Reference these boards often. Go read as many situations as you can. You will see a common theme with the WAS. They all act the same and read from the same script.
