I have an 18, almost 19 year old son whom is homeless. Recently my husband and I gave him our old van so now he parks wherever he can and sleeps for the night. He has a fulltime job amd makes pretty good. He has substance abuse problems so he is ALWAYS broke... My question is how does this happen to smart and talented kids? And why can you never get them to see reason? We didn't raise him like this! I keep trying to figure out how I screwed up so badly! I was very strict but my husband wasn't..at all! I'm at a loss and I don't know what to do!
