Input: So sometime ago we were watching her instagram and  we found a pic about a guy, everything is ok. Then she said "this gut tried to flirt with me". 

By some reason, I feel strange. I do not doubt of her and he doesn't suppose any danger for the relationship, she would never have anything with him even if single. But I don't feel comfortable with the detail she follows and likes pictures of someone who tried to flirt with her (she always likes everyone pictures). 

I feel this is silly thing and I'm not going to make an argue about this with her but I wanted to ask AITA for feeling strange about this? This is not killing me but there's a slightly uncomfortable feeling.
