This probably doesn't help you, but you're not alone. There is something wrong with men nowdays. They can make a lifetime vow to you, in front of friends, family, and God, then after ten years his gets a little unhappy and leaves all we have worked for. I so lost and confused myself. I would never have left.
Feelings come and feelings go.
I think this pain will last forever. I would like to curl up in my room until everything is back to normal. I wish you well.
