One of my friends who's been recently married usually discusses things about her insecurities. According to her, her hubby's the girl-magnet type - he's someone who doesn't even have to talk to get a girl notice him/her from a distance and approach him. She always say that she trusts him but like what they say, "Trust God, but don't leave your car open in the parking lot.", she wants to make sure that he won't cheat on her.
I'm not yet married but would like to help her. Can anyone share some piece of advice about this matter? What would you suggest her to do if she wants to make her stay loyal to her?
