Wow you have been going through this for 4 years? I have to agree with you its perhaps time he went. The final time I kicked my son out yes I thought he would die (he has been resuscitated twice) but he was slowly killing me as well. I live with my daughter and granddaughter and his behavior was causing a lot of stress on everyone. I also feel I was enabling him. If he always had a home to come to and family I could save him, wrong......also I did not want drugs or anything related to them in my home. You need to be strong and stand by what you believe in and strong for your husband as well. Yea the tears pull at your heart strings but they dont last long. You know in your heart what is the right thing to do, good luck, be strong.
