Shameful Secret

I never thought I'd end up here. Last week, my husband was away for work and everything felt so quiet at home. One night, I found myself sneaking out to a nearby hotel to meet an old college friend, just to talk, really. But the drinks flowed, and we ended up in his room... it wasn't planned or anything, but something about being there alone together brought back all these feelings from our past. We didn't mean for it to happen, I swear, but one thing led to another and we slept together. It feels like cheating even though he's not my husband, now I'm terrified of what this means for us.
