Should I be upset with my husband ?

Sooo basically i was just on his phone on Facebook and i seen a screenshot message he sent one of his closest friend..it was a Facebook memory screen shot from 2009 some girl said “ily :)” “i love you” and he said to his friend in the message “ she been trying to talk to me, I should’ve hit” like what… am I overthinking? Should my feelings be hurt? Like why would you tell your friend you should’ve had sex with some girl from years ago and you’re married.

I’m not gonna say anything to him but that really made me feel some time of way. What would you do? But then again he said should’ve hit not I want to hit
