Many girls smile and flirt when they find a guy attractive, and this happens irrespective of whether the guy is in public with his girlfriend.

Girls are visual too.

When they aren’t in a relationship and so happen to see an attractive guy in public, they get excited.

They smile at him, hoping that he sees them.

They flirt, wanting him to get the perception that they are interested in him.

Yes, you are right there with him in public, but for many girls, this doesn’t matter.

If anything, your presence creates a spark of competition.

Human beings are innately selfish.

Once we see something we like that is physically appealing and affects us emotionally, it becomes all about us.

We forget or conveniently ignore the fact that this person is taken, as we want what we want.

Some girls are more subtle with their admiration, while others are unabashedly obvious.

Listen, your boyfriend is attractive and this mustn’t be lost on you.

The truth is, his attractiveness is what you first noticed about him, and played a heavy role in why you chose to make him your boyfriend.

His good looks don’t suddenly disappear to women at large, now that you are in an exclusive relationship with him.

The same physical appeal that you saw in him when you first met him, is the same physical appeal that he has today.

You are not the only one with eyes for him.

Girls who smile and flirt with your boyfriend when you are in public together clearly see that he is with you, and this, in and of itself is compelling to them.

A guy that is attractive and taken, is that much more attractive to women.

He is the forbidden fruit, and they love the challenge of winning him over from his girlfriend.

Remember when you were a child and a person in authority, such as a parent or teacher, told you not to do a deed and you did it anyway?

That mentality doesn’t entirely go away as an adult.

It’s alluring to go after what is regarded as off limits.

When these girls see you with him, they see you with the forbidden fruit.

There is a trigger of desire that sets in.

They realize that he is someone that is taken.

Someone taken is someone that was chosen, which makes said person desirable.

Not only is he attractive, he must have qualities about him that made you choose to get into a relationship with him.

These thoughts go through their minds as they assess your boyfriend.

Since they believe that this guy must be a gem, inside and out, due to your choice to be with him, they assess you.

They give you a closer look, examining you, and comparing you to them.

They realize that you are not as physically appealing as you should be for this special guy that you are walking arm in arm with.

He deserves better.

He deserves one of them, not you.

This is how they have made you irrelevant in their minds, justifying their reasoning behind smiling and flirting with him, even though you are right there with him in public.
