My ex treated me like a princess at the beginning too. Then he flipped a switch and all that stopped and the drinking went into overdrive. Alcoholics are con-men and con-women. Sorry to say this but it is somewhat of a red flag that he's 50 and has never been married. Wait, and he has roomates at 50 yrs old!!? Bigger red flag. He sounds like a carbon copy of my ex who was definately an alcoholic.
