Time is on my side

"The timing wasn't right". This sentence got me thinking about how people abuse the concept of timing, in their interpersonal relations.
Is it ever about the timing? Or is it just an excuse we use? When we say "the timing is not right for us to be together", don't we really mean that we choose not to be with that person?
What I mean is: what we're really trying to say is less along the lines of "Time/life/fate has played a trick on us by putting an insurmountable obstacle in our way, one that we can only overcome separately, instead of together" and more along the lines of "Being with you is difficult/unsatisfactory. There is a better option on my horizon and I want to explore that instead. Maybe if that option wasn't there, I'd settle for you."
The timing excuse to breakup a relationship has the added bonus of leaving things in stasis - people convince themselves that if/when the time is right, they may get another chance to make things work.
I don't believe that timing is a factor in a relationship. Time, yes, most definitely. Like Henry van Dyke says “Time is too slow for those who wait, too swift for those who fear, too long for those who grieve, too short for those who rejoice, but for those who love, time is eternity.” Time is to love like the wind to a flame :Il vento spegne le candele e alimenta l'incendio - which is to say, wind blows out weak flames and blows up strong ones.
But timing? No, timing is a matter of choice, in my perspective. It may be a rational, conscious choice, or it may be an emotional, an egocentric choice - to put something, or someone else first; to decide to experience another situation instead.
