Wow Peace! That's really something. He gave up his kids too! It blows my mind how someone - anyone - can abandon their kids.
Your XH loves his alcohol more than anything else, I guess. No room for anyone else. My H has admitted to drinking too much, and I gently asked him about it yesterday. He didn't go into it much, but he did say it's easier to escape (or something to that effect - can't remember exactly). He added that he was not drinking in the morning, he didn't need it to start the day. I just left it alone. That's his journey. He was not historically an alcoholic. But, as I found out many years into our marriage, he certainly has addictive tendencies - his drug of choice Porn and sex. Now he's adding alcohol to the mix. I almost feel sad for him.
