Along the lines of what you've mentioned about 'when', there's no one else that will match this one, that you feel 'rejected' by.

Well, let me play out this little scenario.

What if?!

What if, right now, you are in need of developing who you are, resolving your personal demons and finding your place on this journey of life.

What if, right now, MR. IATE, is going through his own struggles and turmoils? What if, he and you aren't meant to be here, right here, right now, until you've both reached a point in life, where you enter each others lives, and can reflect back and say wow, we were both going through too much, at those times in our lives, that it would detract from the future of the relationship.
A point in life, where you can both appreciate having each other in it! Really, truly appreciate having each other in it.
What if, these struggles are all meant to develop you into the people you will become?

I have hope your MR. IATE is out there for you. Waiting for that special woman to come along, struggling with why isn't she here, right now? But what if he's also struggling with emotional stuff right now?

Imagine, two relatively healed souls coming together, in the future.

Just a thought, as I consider my own set of circumstances.
