Husband dated a stunning model/stripper

Okay, please don't give me hate for this! I just need to vent out the feelings.

There is a girl I am loosely friends with that I met through my husband. Her best friend (I've never met her), is a gorgeous nude model and stripper. She has been on the cover of several magazines including Tattoo magazine. Total babe, can't relate. I do get Instagram recommendations regularly to follow her, and this leads to me scrolling through her pictures feeling like an insecure whale (I think we have all been there).

Anyway, I mention this girl randomly last night to my husband (feeling insecure and venting to him - I know it is toxic to compare ourselves to others, but it was one of those days). He knows who she is. He also has a weird look on his face... and after some questions I learn that he dated her before we met. I feel sick.

I know our partners have histories and we can't make comparisons or judge or get upset or WHATEVER. But there is something about learning my husband dated this girl (basically a sex symbol) AFTER she was already someone I've envied and compared myself to negatively 😭 It has amplified my insecurities x10.

Now I know he can't change his past, I can't blame him, and I shouldn't compare myself to others.... but I'm really struggling with feelings of inadequacy and a desire to hide in a paper bag. HELP 😭
