He slept on the couch !

Well I love my fiancé  but last night I'm super tired and pregnancy morning sickness looks like it'll be stay this whole pregnancy.He kept waking me up so I got upset and said stop I'm fine or whatever (half sleep) so I guess it pissed him off and he slept on the couch after I fell back asleep and I woke up alone. I know it seems petty and small but I'm not even sure what I did. :/
