I need more space!!

So my husband likes to take about 2/3 of our bed on normal nights.. tonight, he decided he wants to use a body pillow since I have my pregnancy pillow.. I'm literally on the edge of the bed! I keep trying to get him to move by pushing into him but it's not working.. he just scoots closer and tries to cuddle. I barely sleep as it is with the constant peeing and the hip pain. Plus I usually wake up with a Charlie horse and/or heartburn at some point through the night.. ready to kick him out to the couch! All I want is my half!! Is that too much to ask?!?! Lol
