"There are some paths in life we must walk alone and if we meet someone amazing right at the trailhead, we can only hope to see them on the other side."
So beautifully stated, Joyce. Two of the happiest, most loving and mutually supportive couples I know — my parents, and an aunt and uncle — were people that met once upon a time, couldn't get it together and bring themselves to either start a relationship or stay in the relationship, and then went their very separate ways, only to reunite years later, realize "This is The One" — and have been together for decades since.
I do believe that people usually make time and effort when they decide something's really important to them, but then again, look at how many people have self-sabotaging behaviors and just can't help but fail themselves? I think relationships are no different. Some of us find the courage to say, "I'm not sure if I'm ready, but I want to try." Others don't. If it really is the right person, I like to imagine they find that courage down the line to circle back and say, "I'm more ready than I was before, and I want to know what's there."
