Welcome!
He had promised me he would never leave
Can anyone ever really promise that and would we want them to - at any cost?
Is this behavior of an alcoholic mind or just HIS behavior
Some wise women on this board spoke up in my head when you asked this and they responded (or I think this is what they would say), "Does it matter? Really? Do you want to be treated like that for any reason?"
Good luck and stick around,
peace
