Irmat, Stick to business. Child support payments are business. Stick to the facts.... Be nice about it, but be firm. DO NOT tell him you are praying for your Marriage. Do NOT tell him you love him. Do NOT email him. Leave the Man alone.
I am glad you had a nice chat, that is a good thing. If you want to have more of those nice talks, I suggest that you don't spook him by having any type of discussion about your feelings.
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.
