As of May 2010 my wife and I have been married for 19 years. She has 3 children, two boys, 39 & 34 and one daughter 27. I am 8 yrs younger than my wife making her oldest only 10 years younger than me. 3 years ago my wife's 37 year old son came to live with us for 6 months while he saved and got back on his feet after his cross country move did not work out. He has a BA Degree in Graphic Design, has never been married and has no children but come to find out has a drinking problem. When he first moved in he lived in our den, after all it was for only 6 months. I told him the only thing I expected was for him to get on his feet. He did get a job waiting tables 24 hours a week and because his car had been reprocessed he would have to barrow my wife's car. Both my wife and I work 40-50 hours a week which meant I would drop my wife off at her work on my way to work and pick her up on my way home. After 4 months the car pooling was not working out to well so my wife decided to co-sign a loan so he could buy a car. By this time my common sense told me the 6 month plan of him saving and getting back on his feet was not going to happen. I pointed out to my wife and step-son that getting on his feet by saving with the current job only working 24 hours a week and drinking the rest was impossible. I was told not to question the situation nevertheless after 13 months he moved out and in with his younger brother. In Jan 2009 (6 months later) because of his drinking and not working his brother kicked him out so he moved back in with us but this time into a bed room rather than our den. It has now been 18 months, although his unemployment pays for his car, insurance, and Direct TV he has no job, pays no rent, and now uses a walker due to the effect of alcohol.
This all has no affect on my wife however I am going nuts and our marrage is going bad fast. What can i do?
