I was scrolling through Instagram when I saw a post a mutual friend had a video of some random performer on stage with no shirt on dancing in a crotch thrusting way when I scrolled further down and saw my LTR of 2 years was one of two people who liked the post. Wtf this seems like a red flag what do I do? I asked her about it straight away and she said she liked the guy then straight away corrected to I like seeing my friend out living life as in going to concerts. I was like wtf that's weird and it sort of ended there.
