No sleep... About to leave boyfriend

I am freaking hot 24/7. 
When I go to bed I get so hot. I turn the AC and fan on
My bf sleeps on the fan and air unit side of the bed.
He has started to complain.. So I offered to switch sides tonight.
No he says
Ok I turn it on and he huffs and puffs
Dude I'm 33 weeks pregnant 
Next I can't get a comfy position and I'm sweating I go to the couch. 
I can't fit on couch😡😡😡😡😡😡 
I'm legit about to leave him over this
I'm fucking tired as fuck
I just want to sleep in the bed with the AC on.
