When a spouse leaves they should put a separation agreement together... the L will explain this. It does not mean you are divorced, it just puts in legal how the finances and custody arranagements will happen... rather than you just being at the mercy of your husband's "generosity"
This is the proper way to do things, having a proper separation agreement makes things simpler especially if children are involved.
And then step back.
Shut your mouth.
And leave things alone.
There is no need for everyone you know to know all of the details of your marriage and your problems.
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.
