You should trust your man enough to know that he would never cheat on you. Of course, sometimes women try to overstep their boundaries. Since that can make you uncomfortable, here are a few different ways to mark your territory to keep women away from your man:
1. Change Your Relationship Status on FB
Most people will Facebook stalk the guy they like, so if any girls have a crush on your man, make sure he's listed as your boyfriend on social media so they know to keep their hands off.
