SSL,
They say on this forum that lots of A's stop growing at the age they pick up. He sounds like my axh. I say he stopped growing up at 13 years old. He would make faces, say stuff under his breath, and scream loudly so people could hear him. Very immature like. Sounds like he has been sober for a long time but still has the characteristics of a dry drunk. Count your blessings that this didn't take you 2 or 4 years to see and you had more invested.
