A lasting relationship is not a matter of luck or even a matter of choosing the "right one." Even the most promising relationships will struggle if the following relationship skills are ignored. Communication Skills
Skilled communication involves first listening to understand and second speaking to be understood. That means listening with both ears. Try to see things from your partners perspective. Communication skills also involve understanding that your partner cannot read your mind, nor can you read his/hers. Share your thoughts and feelings with your partner. Be clear, open, honest, tactful, and respectful.
It takes skill to learn to show love to your partner in a way that feels loving to him/her. Don't do a Homer Simpson--Homer gives Marge a bowling ball, because he would love to get a bowling ball. Mature love also means behaving lovingly even when you don't feel particularly loving.
Problem Solving Skills
All relationships encounter problems sooner or later. Problems that are ignored or swept under the rug come back to haunt your relationship. Successful problem solving skills will greatly benefit your relationship
Learning how to be intimate in a way that meets both of your conditions for arousal and satisfaction takes practice and skill. Selflessness and an openness to learn can help in developing intimacy skills.
Compromise is not a dirty word. Learning to compromise is an important relationship skill. This means finding creative ways for both of your needs to be met, even when you cannot agree on how to solve a problem.
Fair Fighting Skills
Fighting fair is essential in lasting relationships. Dirty fighting leaves emotional scars that may never heal. Since all couples fight, whether you call it disagreement or discussion, it is still important to learn how to do it fairly.
Finding ways to manage a household that involve a fair and equitable sharing of workload is vital. As is finding ways to share parenting responsibilities.
These relationship skills are all interconnected. For example, fighting and lack of cooperation will affect your level of intimacy and a lack of intimacy will increase the friction in your relationship. Improving these relationship skills will improve your chances of creating a lasting relationship.
