>>2468223Bro honestly you got three options: ignore the signs in favour of marriage as is, confront her and possibly end marriage or encourage her sluttiness and possibly enjoy a revitalised sex life with your long term partner. All three options potentially lead to end of relationship but only one has the potential to be hot.
I had a similar situation with my wife where I found nudes she wasn't sharing with me on her phone. No idea who or even if she was cheating but I ended up planting the idea of her selling pics and breast milk on a local Craigslist clone here in Aus. Was pretty hot. She shared most of the contact she was getting through the site with me (a lot of weirdos obviously), however I ended up creating a few spoof accounts and sending her a few monster cock shots: something she didn't divulge to me. All of a sudden she's buying large dildos and cock sleeves 'to try something new'. Sex life improved. Don't believe she ever cheated and honestly at this point don't care. She's 'discovered' a preference for being stretched and I reckon I could easily plant the idea of a threesome with a big cock if the fancy took me.
