Sleeping arrangements

So we just got our baby sleep in the crib. The crib is in our room. We have two rooms in our house. The spare room has pur laundry and a work space my husband uses when working nights. I'm currently sleeping in that room with the dog and my husband is sleeping in the living room on the couch. He smores loud and was sick. Our room is tight by the spare room. I want to sleep in our room because I love my bed and I'm currently on the floor. My dog is on the bed in that room by the time I'm ready for bed. He is oo big and stubborn to move and he knows he's stronger than me. Anyway I'm afraid yo go on there and try to sleep because he slept 12 hours. I'm afraid of he senses that I'm in there he'll want to be up all night or back in bed with me which isn't happening. My husband is certainly not allowed in because of his alarm and snoring. I'm afraid that I'll be in the spare room until we move which is 8 months or more. Does anyone else have this problem? Did anyone else have this fear and then try and if so what were the results?
