You have a very wise head on your shoulders. I know my exhusband was going through a midlife crisis but having preschool children at the time I thought he was okay since he never said anything and I knew something was up but couldn’t get it out of him. Truthfully I feel he didn’t really know and then it was too late. It was good that you were perceptive and observant enough to see that problems could lay ahead if unattended. Just keep in mind marriage at times is 50/50 and other times 1000% to very little. At this time you’ve been on the upper end of effort. It will well be worth it, since divorce is the much harder road than people seem to realize, rather than try and work things out. Hugs to you, Carol. Keep strong in Him during this trying time.
