Do I reach out to her?

I have been seeing a man for a couple months now. We haven't had sex. Heavy making out, flirtatious texting, and dates. I just did some hard-core digging because some things just weren't adding up. Turns out he is married with 2 little girls (under 4). I'm a little ticked off, not for me, but for his wife and children. His wife is actually a radiology technologist at former hospital. I feel some sort of obligation to reach out to this poor woman but I don't know if it is my place to do so. I am feeling strong girl code vibes right now. What should I do? Reach out or keep it to myself?
