A Slippery Slope...

I met someone new at work this week, just friendly chats over coffee breaks. But we ended up in the supply closet one day, and it quickly turned more than casual... We didn't mean for anything to happen, but sometimes a little tension is hard to ignore when you're alone together. I left feeling guilty and confused because I know my partner wouldn’t approve of this kind of thing at work, even if we have an open relationship. It's just not what I expected or intended, but now it's out there...
