My advice would be to NOT move out of your house, and to sleep in your own bed. If she doesn't like it, SHE should leave, since she is the one that has had multiple affairs.
You come across as kind of needy and pursuing, and if I can feel it thru your posts, I'm sure your wife can feel it as well. That's not a knock -- just an observation. I would recommend that you work on yourself, and let her know that you don't want a divorce but you can't stop her from doing what she feels she needs to do. Just validate without agreeing.
But DON'T move out of your house. She will see that as a sign of weakness, and will lose further respect for you. And women tie respect very closely with love!
