When women aggressively flirt with my husband I usually walk up and say, "Not your husband." and walk off with him. After 20 years together, Hubby and I don't play. He won't put up with it any more than I will. He will rescue me if some guy comes onto me, I rescue him from aggressive females.
I did like the time some woman was flirting with Hubby while we were shopping with the kids. Kids were 18, 15, and 12 at the time. Our 15 year old daughter walked up and said... "GET YOUR HANDS OFF MY DADDY!" She is so much like my Mom, I love that child, she has no fear! I did have to (appear to) reprimand her, I said, "Now Sweetie, you know Daddy isn't going anywhere, he couldn't afford the child support!" Woman backed off quick!
