kimchi01,
you seem so gentle with each other. He may need to be alone because he feels incapable. Financial stress may make him feel a failure. Maybe this predicated by the natural loss of testosterone that men experience in age.
He seems willing to be honest with you, but uncertain of what is going on with himself. He may have an illness affecting his behavior that he doesn't even know about.
But how are you doing? It can't have been easy for you living with someone who has severe anxiety and depression.
Will you celebrate together Friday, honoring the in love years.
Will you leave the door wide open in case he "needs" to return to you.
