Love is obviously a crucial element in a successful long-term relationship.Be honest and never doubt each other. Trust in one another. Love one another and be as one...Communication is important to me,because i believe if something is bothering you about the other person, talk to them about it. Don't let it eat at you and hope that they are going to change...to be open and honest with the person you're with. Lying about things only means you have something to hide, and it only makes things worse for everyone,without honesty in your relationship it will not work..I think the most important key to a successful relationship is when you truly enjoy each others company...I've to stop here now because my fingers hurt and I'll be waiting to read from you.
