No no no! Staying for the sake of the children is never the right thing. If YOU are not happy, then they will not be either. Children are very big empaths. They feed off of you. Don't make excuses. Get out there and start making yourself happy. Leaving doesn't have to mean automatic divorce. A separation could give you all time to figure out what's best. Your children are resiliant. My son still asks to see my XABF and his daughter every day, but I know I made the right decision. Just go over to the adult children of alcoholic board and see for yourself. You are doing well at remaining strong and not starting arguments. Now it's time for you to keep moving forward.
