Why did he do this in the middle of everything?

so me and a guy i was dating were kissing. it got intense and when we both kind of noticed was going further , he got up and went to the bathroom. then came back normal almost.

i was confused because he didn’t ask , i didn’t ask but it was there … he just left and didn’t pursue or ask or anything. just nothing.

then when we cuddled he didn’t cuddle fully. he gave me ample space even when i made moves..

what happened?
