Alone 22 - it is a huge sign to who he is
Couldn't agree more. It has a lot more to do with a persons morals and values than alcohol. A man with HIGH morals and values in his core, will be mindful of hurting you (a once partner he loved) despite agreeing on a separation or divorce. Even if he didn't love you anymore, he would still be respectful and wait until his marriage was over before moving on with someone else and definitely not when still living with his ex.
Separation and discussing divorce and separation whilst trying to work on your marriage are two different things in my opinion too.
