No I wouldn't suggest looking either as it was very very painful for me to find he was doing that....
Might I suggest that you just openly and plainly tell that while other men might seek an outlet via the internet or PA that you would rather talk to her and see if you can work together to create a relationship that is fulfilling to you both.....and let her know this is not about blame and that you are ready to hear if she has issues that perhaps you need to give on and then you tell her the issues that you would like her to give on.... Teen years are tough, then we get married and just when you think you have it made the bridge colapses.....life is never what we plan is it???
