I'm glad you talked to her.
Now we have a new list of potential problems.
Whatever I say here is not meant to dampen your spirits.
It is to help you protect yourself.
She is blowing hot and cold in this new relationship.
Asking her for the reason is not a wise choice.
Asking anyone in this forum is equally silly.
The solution is simple.
Do not ask!
The first sign of a man messing things up in a relationship is when
he thinks to himself,
"I don't want to mess things up!"
The problem I foresee is that you are always planning your
next move, so you will never let up and enjoy
yourself.
Communication is essential.
But conversation has to be spontaneous.
Show her your world and casually invite her
in.
When you probe too much too early, everything tighten up.
I know how eager you are to show that you care for this lost and
found relationship.
If her interest in you is based on a logical evaluation of
her opinions, you would have scored a 8 or 9 out of 10.
But it is not.
Good luck.
