Forgive me if I am out of line but I think it might be wise to tell your wife about these women flirting with you.
I'm one of those whose husband told her that a woman was flirting with him. Did I get upset? No, because I know my husband and he's not the kind that strays (very loyal). He didn't tell me to make me jealous. He told me because he was disturbed by what the woman had said to him, she said that she wanted to seduce him and make me so angry that I would leave him so that she could have him. This was someone that he had know before he ever met me and just happened to see her at a grocery store that I had sent him to to pick some things up. They hadn't seen each other in a while and caught up a bit on what was going on in their lives, hubby had just told her that he was now married and we had just had our first child.
To this day I still don't have a problem with a woman flirting with my husband (well as long as it's not done in front of me) cuz I know where his love, respect and loyal is...with me.
