Dar,
I have a question, and I am not being a smartarse.

Why do you want him back?

You mention you are emailing each other.

Why?

Each time he emails you, how long does it take for you to respond?

You are already talking about the future, the fact that he may live 4 blocks away and you can start working on "us".

As nice as that thought might be, you need to stop this line of thinking.

Again you are having expectations.

Then you will become angry if things don't go your way.

This is the pattern I have noticed.

Can you not just psych yourself out to believe he is gone and you have to keep moving forwards, regardless.

There can be no testimony without a test.
I am praying to go through this test and come out the other end with a new and better marriage then before.
