Lauren. He is using you as his soft place to land. If it were me, there is no way I'd turn over my home and "leave" for a break from this chaos. Instead, I would perhaps pay for t
wo nights lodging in a motel for him to get some distance while I start bagging all his stuff, and have it delivered to a storage unit of his choosing. Enough of the games and lies. He is an addict, and the sooner you get him out of your home, the sooner you can begin to heal. He's manipulative and untrustworthy. He is well into his addiction and you may find your valuables are taken, sold, destroyed. Need I paint you a clearer picture? Get your locks changed. I would wonder with all the current BS if your fiancé is still employed? My guess is not. Cut your losses and run.
