Falling asleep on the couch?

Does your SO fall asleep on the couch a lot? My husband does and it really upsets me. I can understand if he falls asleep on the couch every now and then but he does it a lot. I'm talking like 4-5 times a week. I've spoken to him about it so many times that I'm starting to get a little pissed. He never really has a response and he knows how it makes me feel. How do you feel if your SO does it?
