Caught My Wife and Her Co-Worker In The Act

So I guess this is confession time. It's been a couple months since the incident but it still feels like yesterday. Me, 25, married for three years now to my wife Sarah who's 26, and we've had our ups and downs but nothing too serious. We have a good life together, settled in with two kids and everything. Then last week, I'm at work all day then I stop by the house on my way home from a late meeting since it was Friday. Just to grab some sleep before heading out for dinner that night. You know how sometimes you think there's something off when you walk into your own house? That’s exactly what happened. I smell cologne, not mine, and I hear muffled giggles coming from the bedroom. Curious as hell but also a little irritated since we have kids at home who'd wake up if they heard anything, so I just ignore it for then. Next day, Saturday morning, me being myself, forgetful and all that, decide to go ahead and check out what was going on. I open the door to my bedroom slowly, not sneaking or nothing, I’m married after all, but still, there's Sarah with her co-worker Jane in a compromising position. Jane’s around 29ish, new at work for only about two months, very cute, petite with blonde hair down to her shoulders. It was an awkward scene for sure. Sarah had this look of panic and surprise on her face as soon as she saw me standing there, while Jane just froze in shock or maybe fear. I don’t know if Sarah ever felt attracted to women before but here she is basically making out with one right under my nose. Now they’re not exactly strangers since they bump into each other at work sometimes and socialize a little bit, I figured that’s probably how it started. But still, this was totally unexpected. Jane tried to explain it wasn't anything serious, just “one of those things.” Sarah promised it wouldn’t happen again but honestly? It doesn’t matter much anymore. This was too big of a betrayal for me and my trust in her. So yeah, that's the story. Just something I had to get off my chest.
