sadly i can see myself in him.
with some ex girlfriends, i've found myself thinking, why is she telling me this story and sometimes thinking, she's doing it for the wind up. i have to admit i wouldn't of with a story as innocent as yours but if teh story was " you'll never guess what happened today, a bloke made a delivery to the office and got talking to xxxxx and told her he fancied me " i would find myself reacting like your boyfriend.
some ex girlfriends could tell me things like that and i'd just think, so what and with others it would really wind me up.
