Would you stay the night with your friends with benefits?

My ex and I were supposed to meet up to have sex it didn’t happen that way. I thought we were going to meet up at a hotel but then he said something about us having car sex. He didn’t want to pay to use a room for just a little bit of time if we weren’t spending the night. I thought it was going to be like last time (but this is when we were a couple). We use the room for a little bit and then head out. I didn’t think he’d want to spend the night with me. That doesn’t sound like friends with benefits to me: spending the night together, what do y’all think?
