There's nothing worse than being with a group of friends or family and it turns into a big argument with you at the center. If your man truly loves you, he'll defend you in these situations, even if you're totally in the wrong. The same goes for more serious arguments - if his feelings are genuine he'll stick up for you no matter what. If he does have a problem with something you've done, he'll discuss it with you privately and not in front of a group.
Knowing that there's always someone there who has got your back is one of the best things about being in a relationship. You can stride confidently into any discussion knowing that you have your partner right by your side. If that isn't one of the best things about love, we don't know what is!
