Like you already said there are multiple reasons that go into explaining the reason you were feeling the way you were this morning/yesterday night. More likely than not it is some sort of combination of all of them.

some preliminary reflections:

Because we are essentially alone in the world (no one else knows our day-to-day activities, no one else is in our heads, knows how we see the world etc.) the only way to obtain lasting and authentic happiness/satisfaction is to maintain internal peace and stimulation. This is/will be true forever.
John Doe is an externality that has affected you and thrown off your internal balance. This is not a bad thing. He challenges you. The relationship with him is showing you where you are weak.

As evidenced by your feelings, dependence on another is NOT a pleasant feeling in this context. It's not that you haven't previously been dependent on someone else it's just that it hasn't been an uneasy feeling in the past because you have always been the one who is ultimately in control. He's not reciprocating the way you are used to.

Moving forward I would urge you to keep in mind that, no matter how strong they are, emotions are fleeting. When we surrender to them we inevitably become dependent on them or the person who induces them (and therefore dependent on externalites, things not in your control). To be so entangled with someone else is a very dangerous thing. Nothing comes without a price. What we give up by leaning on someone else is not evident at first glance. It's not usually the case that the person's presence in one's life is the problem, but the leaning that is the problem. Also consider the fact that, more often than not, a person's attractiveness and/or power over you is dependent on the power struggle; you have always won the struggle easily, not so here.

Keeping all of that in mind I would try not to over-think things, try to clear your head and live moment by moment concentrating on centering your mind and the depths of your soul. Enjoy these last few days where you are.

I have no patience
for your fear.
Push me.

Not doing what,
not giving what,
I wish you would.

Do not
forget
it is the human condition to seek a companion.

We are willing
to push
and pull
to see
what we want
to see
in someone who demonstrates sexual potential.

Over-exerted “honesty” becomes authenticity lost.
How easily
we forget
the beauty
of silent understanding.
We rush
to define
and complete
our story.
...

A man
His hands
Wrapped assuredly around your waist.
He is certain
of what he wants.

You remember
that you
are a woman.

All of that time
you spent
trying to forget.

In the end
You find
the arms of a man
attach
to
the mind of a boy.

In the end
you are
dissatisfied,
always.
Interest fades.

I cannot
entertain
not
worth
the energy.

And as you get older the differences begin to augment, you sit and you wonder and nothing is the same. Those that do not push forward fall back, slowly at first and as time passes the gaps become larger.

Pure.

And it was he that made me realize that I don't love you.
Not that I couldn't but that I don't.
That he could make me feel that way made me realize that you don't.
What I felt for him wasn't "love," whatever that is.
Yet, a fragment of the feeling was powerful enough to pale our physical connection in comparison.
Pure.

The rule of law exists only so long as we believe in it.
