horriblethisis---if you are looking for some "easy" way out--there isn't one. Not totally painless. Sometimes in life we are required to do some things that simply are not easy.
This is how I see it: You can break it off now.....or......wait for him to mop the kitchen floor with your heart, later. The choice is yours.
Either way--it won't hurt him too much. He will reach for the bottle and numb anything that he might feel. Either way--he gets to keep his first love--the bottle.
sorry to have to put it this way...but, it is just reality of life when you live with an alcoholic.
