I am confused.

This was sent to you?

Or this was something you found while snooping through your wifes stuff from her Mother?

So this is what your Mother In Law thinks of you?

How much of it is really accurate?

So do you think that some of the things she thinks about you may actually be true?

Maybe this is a wake up call to start making those changes that need to be made.

Your wife has obviously been very unhappy for a long time, and I wonder if you ever really noticed her cry for help.

In everything there is an element of truth.

Have a heart to heart with God, and ask HIM to show you where you failed your wife.

And BT, DO NOT RESPOND to the email you found.

It is none of your business.

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.
