Divorced and Dating Again

So, I recently got divorced after seven years of marriage. Not because we weren't still into each other or anything, but let's be real, when you're in a relationship that long, sometimes there are just more questions than answers. Plus, I always had this feeling like maybe we were doing it wrong and not living up to the full potential of what we could be. So I decided to take a break from being married, officially become single, and start dating other people. The first person I dated after that was Sarah. She's in her early thirties, has this great sense of humor, and she gets me like nobody else ever did. We started slow, just coffee dates and walks on the beach. Then it kind of escalated pretty quickly into a full-on affair. And I loved every second of it. The funny thing is, even though we were both consenting adults and everything was consensual from the start, there's still this little voice in my head that goes 'Is this okay?' because it's not exactly following societal norms for divorce. Like, what does that make me? Am I being selfish? Disloyal to my ex? But then again, Sarah and I never agreed on any sort of labels or boundaries either. It was just...us. And it felt right. So here we are. I haven't told anyone about this but now I'm considering whether I should come clean with people around me, including my ex. What do you think? Am I being an asshole by keeping this a secret?
