AITAH - i saw my housemates boyfriend in the bathroom, i told my boyfriend thinking he’d find it funny. he did not

i live in a house share and yesterday i saw one of my housemates boyfriends using the outdoor shower round the back of the house (we live by a beach)

my bedroom overlooks the back of the house and like, i didnt stop and stare but i did see everything.

my boyfriend came over later and i told him thinking it was funny. but apparently i told him too many details or i sounded too impressed and now he’s ‘sulking’ and bought up ‘insecurities’

so, AITAH ?
