Having a hard time getting a restful sleep with my boyfriend.?

All he needs is like 5 or 6 hours of sleep. I need like 8-9 "solid" hours of quiet time. He loves to snuggle really close, have the room colder than I like, talks to me in the middle of the night, he snores, moves around a lot and likes a night light. I like it totally quiet, all dark, very warm and be able to spread out my body around the bed. He hogs the bed and I have this small space and I am unable to move my body around and stretch it out like I would like to. I go for days dog tired and I am starting to get really crabby and irritable. I am not getting my REM sleep and am finding it hard to concentrate and am not alert anymore and I find myself nodding off when I sit down for a time when I go somewhere. We have a queen bed, should we get a king or super king bed. Will this help.
