If you define the success of a relationship as being one from meeting until death and happy (as the normal relationship can allow) then you will only have one successful relationship. Maybe two or three if your spouses continually die before you (if you murder them it doesn't count). Some people will never have even one. That sort of love and bond is not guaranteed. Now, if you consider a successful relationship as your survival of that relationship and many important lessons that you actually will apply in your life then you might have many under your belt. Those are * though.
