Love is a process.
Love is a commitment to the process.
Love takes a love of the process.
Love falters when the the process becomes misaligned. That is to say, when one side is either further ahead or farther behind in the process.
Love falters when either side is not committed to the process. That is to say, of keeping the process on track.
Love falters when either side no longer loves the process. That is to say, when either side is unwilling to do the work that love takes.
Love that is immediate, quick, instant, or effortless is likely not love. Love is not a sensible default. Love is a final choice. You may know that love is possible right away and you may begin on the process immediately, but you will not yet know what love means or what the process holds.
Love is slow. Love takes time. Love takes effort and commitment. Love means a love of that effort and commitment. Love means taking the time to build and know and love the process.
Love is a process.
