Married man flirting with me, should I call him out?

I recently had a man come into my work and very blatantly flirt with me. Albeit somewhat vulgar at times, but I enjoyed the attention. Considering he was a bit older than me, and his son was with him, I asked if he was married. He told me no and he never had been.

Obviously I was at work so I wasn’t going to be too forward with him, plus I was trying to make a sale. He did end up buying some things and proceeded to come back multiple times over the two days he was here (we were having an event in town). Each time he sought me out to flirt with me, and I enjoyed the attention.

My manager texted me on my day off to tell me he had to cancel his order because his WIFE was going to kill him if she found out how much he’d spent. Now, I’m not entirely surprised considering he was fairly intoxicated when he came in, but he certainly didn’t seem that trashed.

I’m debating on contacting him to tell him off because how gross honestly? I have his information because of the sale that took place but I don’t want to overstep my bounds here.

What should I do? Should I send him an email?
