My husband's friend likes my selfies?

Revenano
I don't wanna make a big deal of this but I find it kinda weird. 99% of the pictures I post of myself on Facebook, my husband's friend likes them. I posted one today and the friend was the first to like it. If I do say so myself, it was a damn good photo. We are friends but we're not really that close anymore. When my husband saw that he liked it, he said "ooooh (friend's name) has a little crush on you!" Like in a teasing way. It was weird because I figured that if he thought he did, he'd be kinda mad. I asked him "so what if he does that doesn't make you uncomfortable?" Because I would be if it were my friend. He said no, he knows a lot of his friends have a thing for me. I just found it weird because my husband is definitely the jealous type and this is the first time he's mentioned anything.
My questions are:
What does it usually mean when a guy "friend" likes your selfie?
And would you feel weird about it if your friend had a crush on your SO/ if your SO's friend had a crush on you? Thanks!
