What makes a relationship great? Why do some just fall apart so quickly.? I was talking with someone recently and this is what we came up with. First I think both people need to want the same thing, so one can't want a FWB and the other want marriage. Second I think a great relationship is like a three legged stool based on Respect, Trust and Communication. If you don't have all three the stool won't work. Last it takes hard work and a whole lot of effort so the relationship continues to grow and develop, if not it will wither on the vine.
