Not gonna lie you shouldnt sweat it as much. Woman's attractivness is based on 2 levels. And ussually they are actually more likely to be on the lookout than men are. Because Men's attraction has only 1 level and it is directly related to having sex. Women's attraction is a completely different animal. A womans's attraction is more like a cat with a string. Woman's first level is what I call the circus performer level because its completely based on whoever is demonstrating the most social value in a situation. Looks dont matter as much as DHV's. For you you could be taking her out to dinner and in the given frame a circus performer could be the most attractive person her eyes at the moment,because hes the one the with most Social value at the moment. The thing you should be focusing on is her investment. This is the second level of attraction for a woman. Onc ea woman becomes invested this is where those serious emotions start to latch onto a guy and lead to sex. As long as her investment is with you you will have nothing to worry about. Her looking is a natural thing you cant avoid just because society does in fact demand attention from us without our choice. Advertisement will be everywhere. Dudes will be there. The saying is attraction is never a choice, but seduction always is.Her investment is what you should be on the lookout for. If she is investing and trying to actively engage with other guys in front of you then you gotta be talking to her to calm it down a little. Because that means that shes searching for something that your not providing that she beleives you should. Otherwise that's a natural thing and you shouldnt get too butthurt about it. Woman are naturally unfocused creatures unless taught otherwise, they like to be found in the most fun of places and generally want to shy away from being in the alpha frame total responsibility frame. So as a guy just have fun with her unfocusedness and you be a little unfocused too just so you can level the playing field and have something to joke and talk about. People watching is one the best bonding DHV's out there.
