Many women find themselves dealing with other ladies in their partners' lives--or, at least, women who would like to be in their partners' lives. In cases of cheating, you may have found yourself blaming these women and labeling them “mang-aagaw,” the goal being to get your man back and establish he’s yours. It’s good to remember that, more than being a “me vs. other woman” scenario, situations like these revolve around you and your man trying to make your relationship work.

Before he even considers cheating, it’s important to lay some ground rules in your relationship. Let your man know that he has responsibilities, and make sure he understands them. That way, when boundaries are crossed, you’ll know it means he doesn’t care enough to adhere to them. Female Network lists down five laws you should lay down in your relationship when it comes to third parties. Remember that this applies to you too! Relationships are partnerships for a reason.
