I don't used social media much and most of the time it's related to a few hobbies and interests I have. I recently posted a photo of me and a friend. A guy I follow l, who has a similar interest liked the photo. Later that day he sent me a message saying he's shy but thinks I look cute in the pic. We have messaged before, but just friendly chat about our interest.
I told my friend and she thinks it's creepy and to block him. AIBU to take it as a slightly flirty gesture?
