Hi, kremit. Don’t have much to add, just wanted to reiterate again what everybody’s been saying: First of all, big sympathy here, I’ve been in a similar situation (though not living together), and it’s no fun. Second, please get out ASAP; you can’t possibly start healing and recovering while you’re still tangled up in this mess (or, as I put it to my ex-fiance, “How can I get over you when you won’t have the decency to go away?”) Until arrangements can be made for one of you to move out, he sleeps on the couch. Period. Don’t be mean, but do be tough, and stand up for yourself. Best of luck, sweetie.
