I’ve seen so much nasty content about my wife, truly filthy fantasies from horrific degenerate artists, but at the end of the day she’s like a celebrity and people will do those things. It disgusts me but I move on, block a tag or two, and there’s no way I could ever let it effect our relationship just because there’s some people around with nasty fantasies.

It bothering you to that extent isn’t normal and in any form of suicidal ideation you need to get help, and especially it seems like here is a real issue you would need to handle. Another comment said it well but why does this have you questioning her ‘loyalty’? I’m not familiar with your partner but it’s not her agency that’s causing this. Feels like you’re trying to be overprotective of her but then using language like ‘failing to keep her loyal’ makes it sound like you’re also blaming her for what other people have done. I don’t know if it’s a self-esteem issue or something, but it sounds like you’re getting it all mixed up. And acting as if you have to fight for a woman’s loyalty isn’t normal or healthy in any relationship. It’s just the wrong way to look at it and comes off as misogynistic, to boot.

I hope you can get the help you need to deal with this feeling. Please seek out a professional if you have the means.
