Do you think I am being too harsh with my cancer friend?

In the past 4 years I've been through a lot of emotional turmoil in my life, but I rose above it. I now have a great career, I live in a very nice neighborhood, have a new car,have an awesome apartment, and a very loving boyfriend. However, a friend of mines is a serious alcoholic. He has been for 15 years, but has hit rock bottom due to the economy. He has burned a lot of bridges to the point where is own family don't even want to be bothered with him. It's like if any type of stress comes his way he can't handle it. Getting sh!t faced helps the problem. My patience has been wearing thin with him. He's now got two different women pregnant and he no source of income. He told me that him having children will probably solve his alcoholism. I wanted to slap the hell out of him for saying that. I've loaned him money and let him spend several nights at my place before. A couple of days ago he asked me could he live with me for a couple of months till he gets on feet. I said hell no. There are sooooooooooo many alcohol and narcotic recovery homes he can go to and stay there rent free for at least 4 months. Plus they provide food and even clothing. However, when I suggested this he told me to go phuck myself. I told him to never ever call me again until he decides to start acting like man instead of boy trapped in a man's body. I worked too hard for anybody ruin what I worked so hard for. I'm a pisces btw.
