The key to having a healthy and loving relationship is to learn how to accept your fault when you did something wrong without being told: And to be able to apologise without being asked.
Don’t ever be intimated by the success of your partner. In a healthy relationship success of one is the success of other. Don’t feel inferior because your partner is more successful than you. Learn to give your support and encouragement to spur your partner to even greater height. If you can do this they will believe deeply that the success they have achieved would not have been possible without your presence in their life. They will give you credit for their successes and you will both enjoy the benefit of the success. Push your lover to become a better person in every aspect of their life.
Relationship is about living together not just being together. Living together involves growing, learning, getting better and accomplishing great feats together. This creates stronger bond than just having feelings for each other.
Trust is the bedrock of a healthy relationship. Learn to trust but never trust blindly. Make effort to verify the trustworthiness of the person you are trusting. You verify by paying attention to little things they do, say and left unsaid. Verifying prevent you from getting deeply hurt if your partner aim was to deceive and take undue advantage of you through the relationship.
Never should you embarrass your lover privately or publicly. As a lover your words carry weight. Don’t say things that will damage their self esteem or hurt their feelings. A relationship is a place where you build each other up not tear down each other. Treat your partner with respect everytime most especially in the public. And they will love and respect you more.
