Very very sad story of your friend. I'm shocked to read behaviour of her husband. I pray for her and for her daughter. I think she love her husband but bad habit of her husband is hurdle between between she and her husband. I think that wine drinking, cigarette smoking, wrong way of attraction with any other he/she without life partner is destroying domestic life.
If we will not stop ourselves from the above bad habits we will not be able to continue our "Heaven's made life."

You have said right that marriages are made in heaven. But this our duty to continue to give love and respect to our life partner. We should be always faithful in love.
