Competition is not ideal in a healthy relationship. It breeds a hostile atmosphere. Relationship is about togetherness not battle of the sexes. Relationship is not about fighting for which gender is superior. Healthy relationship involves two partners supporting and understanding each other. The right mindset in a relationship should be to see the failure of one as the failure of all: And same for success. Partners should encourage each other to break boundaries not compete with each other for who will be more successful and richer. See your partner as your team mate not as your competitor. When you support each other, you will grow, succeed and stay together.
Be careful of who you tell everything that happens in your relationship and who you run to for relationship advice. Most people you see as friends are not really your friends. Oftentimes they get jealous and bitter when you tell them about the happenings in your relationship. Most times your friends wish they have the kind of relationship you have that you are still complaining one or two things about to them. Human are naturally jealous and envious when they see people who have what they lack. And very few people can keep their jealous/envy under control, most people usually allow it to control them. This fact can make your friends give you advice that will make you do stuff that will ruin your relationship or even snatch away your partner from you. So before you take advice from a friend, you should always ask yourself will it help improve your relationship or make things worse.
Faithfulness is becoming a rare trait these days. If you want a faithful partner you must first choose to be a faithful person yourself. Then you must be determined never to settle for a cheating/unfaithful partner. Work on yourself to get to the state of mind when you tell a cheating partner to be faithful or lose you irrespective of how much you love and want to be with that person. Grow and develop yourself in every aspect of your life. When you work on yourself to become someone of great value it will become difficult for you to tolerate shit in a relationship. Make yourself that partner that brings value to a relationship apart from money(man) and your body(woman). Make yourself that partner that someone is afraid to lose because it will be difficult to replace him/her. Be a faithful and value adding partner.
