Hi Joplus3. You came to a great place. This forum has helped me through many tough times.
I'm 45. 3 kids ages 17, 13 and 6 (boy, girl, boy). Pretty close to your children's ages. The 4 of us left my AH about 16 days ago. We now live with my parents, 7 hours away from him.
Life was hell with his drinking for 7.5 years. In the past few months, everything worsened very quickly. I got out while the going was good. My kids were thrilled to get away from AH, and they have been thriving in our new home and their schools. I'm having a few ups and downs, but it's early days. Overall, things are 110% better.
Remember to take care of yourself, and aim for the life you truly want for yourself and your children. You all deserve to be happy. Keep posting and vent when you need to. It helps tremendously. (((((Hugs)))))
