Girls how would you feel if your supposed boyfriend did this?

[miss bliss]

Your boyfriend and every other man on earth (including your future husband, should you marry) will at some point find themselves attracted to another woman. It's biology, it's fact, it's nothing to be feared. You are aware of certain male characteristics that you -personally- find attractive, right? In the amount of time that you've been dating this boyfriend, could you safely say you have found yourself attracted to a different boy/man at least once? If so, stop worrying. Be the girl who knows she's got something about her that the person she's dating is attracted to. Bonus: confidence is attractive -- another thing for him to like about you!

You'll be happier, he'll find you logical and irresistably confident, and it will all work out in the end.

So in answer to your questions:
1.) Yes, I think you are over-reacting, but it's not your fault. That's how most women are raised to feel.
2.) I joke with my husband about the women I catch him eyeing up. I tell him which men I think are attractive. Then we have amazing sex and are reminded, again, how awesome it is to have each other.
3.) I would probably comment in reply to a picture I found my husband "liking" on Facebook. Something like, "Haha yeah I *bet* you like this one, huh?!"
