1) Good Communication: Be Expressive & Honest (Don't bite you tongue, discuss your disagreements and resolve issues together without involving other people)
2) Consistency: Constant Attention & Commitment (No ghosting or bailing out easily)
3) Reliability: Being a person of your word and Trustworthy (Don't say something & NOT do it)
4) Reciprocation: Treat your person how you want to be treated (Don't dish out want you can't handle, take the other person's feelings into consideration at all times)
5) Respect: Think of your person in high regards (Never speak negatively about your person to anybody and never argue in public, No disrespectful name calling)
6) Trust: Be committed to your person and secure in your relationship (Be truthful and never assume anything is going on without solid evidence)
My wife & I apply These 6 Principles to our marriage and they work for us.
The Healthy Relationship Formula:
Good Communication+ Consistency+ Reliability+ Reciprocation+ Respect+ Trust= Love (Result)
