I’m completely shocked!

I had met this person online and we went out a couple of times. Out of the blue he says he’s going to start seeing other people because he doesn’t think we are compatible. It’s been about 2 months since the last time we talked, but I just found out he’s MARRIED! Through social media since it’s connected to his phone number. Should I say anything or just go about my business? I don’t think his wife suspects anything.
