I can only speak for myself..Finally ending a 38 year marriage. It's not going to get easier. For me, making that decision was one of the hardest decisions in my 62 years of life. That was gut wrenching. However, once you figure out that YOU deserve better, the guilt decreases. Your daughter deserves better! When you focus on making those two things a priority in your life, the balance changes. It's a process filled with tiny baby steps and the slow process of detachment. I will tell you, detachment was a life saver for me. Once, I experienced the peace in my life, I wanted more. It was easier to make important decisions. I started to focus on the positives in my life. My priority was no longer the chaos of the world of the alcoholic and it was blissful. There is light at the end of this long hard road.. Good luck and we're here for you.
