Where have been? I was hoping to get an update when I came here. Let us know how you are doing. I just read the last thing you wrote about how committed you were to your marriage. I have been separated for almost 3 years, bomb dropped over 4 years ago, OW in the picture for almost 2 years and divorced for almost a year. I am still just as committed to stand for my marriage as I was when this started over 4 years ago, actually more so. I have not even taken off my wedding rings. So you are not alone there.
Let us know what is going on.
Everything happens for a reason, maybe Dad needs to find that it isn't better out there, he needs to realize how good he had it here. Maybe he will find God and that is the most important thing when he finds Him he will know he is supposed to come home.
