Just an alternative view of his actions lately. I wonder if perhaps the gravel etc...that's him easing back into his committment to the farm and your business. And perhaps re-committment to his marriage is in the future but he's just not ready for it yet. Maybe this is a baby step?
Just a thought.
I also agree with the others though...it seems that you've been taking things badly lately. I hope that you can work your way through this dip and get to a place where you are happy, strong, and comfortable again.
