Should I say something?

I use FB marketplace to get household things here or there. I met this guy who was bringing me an item that I needed to paint my home because he was selling for $45 and it cost $80 in store but anyways. . We meet up at a populated location(Walmart) to make the exchange so after that I tell him to let me know if he has anything else that he might need gone since he and wife are moving, moments later he messages me trying to hit on me saying he hopes he finds something I need so that he can see me again! He said he knows he is married but still wants to have something, should I give his wife a heads up (just in case he is doing this to others) or no? I already blocked him by the way
