Don't let that deter you from making the best choice for you and you son. We alcoholics are masters of manipulation.
Your first option for living circumstances doesn't sound very fulfilling. Your second option sounds like what you and your son need. I had a stressful childhood but the one thing that made it okay (and kind of great) was my Dad's extended family. You and your son need support, company and love. Your family sounds kind and supportive; take advantage of what they are offering.
