I have found out my SIL husband is liking raunchy photos on SM. Not just one or two but ALOT. These range from celebrities/ women with a big following to women on onlyfans to just normal girls with no following.
It's the liking of normal girls photos that is worrying as the majority of these girls are from the area that he grew up in and still visits often to see friends/ family.
I'm worried about telling her as they have two small children and SIL is currently struggling with signs of PND and I obviously do not want to add to this especially as it could be harmless. I am disgusted that he's obviously spending his time trawling SM looking at these pictures and interacting with them in the form of liking pictures particularly his wife is struggling so. However I would like to think this is just harmless and for some reason this gives him the kicks he needs in a time which is in no doubt difficult for him too.
OH says we should just stay out of it as it isn't our marriage and I see his point but SIL is one of my best friends and I think I would want to know.
So AIBU to tell SIL what I've seen? Do I just leave it? Or do I have a secret word with him?
