Interesting that he’s made you both responsible for him and a prisoner of him. And what about you and where you want to go and do? When do you get to follow your path? You get to stay there, your life on hold, while he gets to do everything he wants with no penalty. 

Paraphrasing Dan Savage here - DTMFA - Dump The Mother Fucker Already. Enough. If he checks out, or not, you are not the culprit. He’s going to stick like Saran Wrap to you because he’s got nothing in his life. 

Make a plan. Squirrel money away in an account he knows nothing about, (you’ll have to disclose it during the divorce), find an apartment, move,  forward your mail to a PO Box. Hit him with the divorce papers. Time to find the right guy for you now!
