Every time partner comes back from a conference he has new female and male followers.
Anyway I make him this welcome back dinner and during the meal he says he met this Spanish woman, Maria, with natural red hair and got talking to her about if it was natural (because it's unusual). I also am a natural redhead. Meanwhile she complimented his hair which is also impressive and the main feature he likes about himself.
I joked I'm glad you enjoyed your time flirting abroad while I was busy at home and he laughed it off. Now I notice 'Maria' 'favouriting' his professional posts.
I trust him and vice versa and he always checks in before bed during these trips but AIBU to think that encounter above sounded flirtatious? Why bother telling me about it?
