ALJ, sorry you are here... I came across your posts today and I think you are doing fine granted the circumstances. Did you H travel alot for work? Has he said he is moving at the city he now lives for good? Has he been there before? How do you handle the finances? Does he support the kids?
It's good that you are talking to a DB coach. I have never done it but all my friends here said they are greatly helpful.
I agree, I think your H is having an affair. All those comments he made about "what if I find someone" etc etc, are all script as we say here. That doesnt change what you should do right now but it does mean this situation may last much longer than what you are anticipating.
For now, keep taking care of yourself, find yourself, know that you will be ok in the end no matter what, and be strong. Good Luck K
