I learned recently about a small little thing called the "Relationship Triangle."
Apparently, the three key elements to a relationship are:
Hope is having the energy to do things when I do not have trust or faith.
Faith being a mental decision to believe.
Trust is a goal, an outcome. Trust is the absence of conscious thought – I do not have to think about it. Trust is NOT something I can MAKE happen. (I.E. I trust that the sun will rise every single day in the East.)
Without these three elements that support each other (when one is weak, the others are strong), a relationship cannot be healthy, it cannot survive and it definitely will not be fun.
