-I think the absolute best way to handle this situation would be to allow your girlfriend;wife to handle it. Stay cool. ( I doubt tho)

The Guy: You can easily defuse the situation not by making a physical point of being her boyfriend, but by simple friendly conversation and an easy-going cohesion/union between yourself and your partner.

After all, you will be approached at times, she will be approached at times; it’s life and it shouldn’t be made into any specific spectacle. Ultimately, this mindset comes down to trust. If you have trust in each other, you have no reason to feel alarm in these situations, they will only make you strong.

After all, the guy hitting on her might be a good dude??
>Now this next part is very important. After he walks away, you have to say something sweet or sexy to your girlfriend/wife. She’s obviously special because you’re with her. And she’s obviously attractive because someone else was hitting on her. Don’t down play it. Play it up. Say something like, “well I can’t blame him.” Then pull her close and whisper something sweet into her ear. Usually when they apologize I tell them not to worry about it because it happens.
OR
Depending on how pushy the guy looks, I either let her handle it, or I walk up and introduce myself nicely and with a handshake.There is nothing wrong with another guy thinking your girlfriend is attractive, if anything it’s a compliment. It’s not like most people just know automatically that my wife is is married. Getting upset and jealous only makes you look bad and ruins the atmosphere.
In these situations,
Trust your lady to respect the boundaries that you and her have agreed upon. Trust is the most important part of a relationship after all! If the person hitting on her doesn’t respect her boundaries though, then it’s probably appropriate for you to step in. . .blah blah

WHATS YOUR OPINION?
