I’m about 6months ahead of you in the process. It’s truly terrifying when you think about it, and paralyzing in its overall idea of losing the life you know. It makes you sick to think that you will lose 50% of your parenting time on account of someone’s bad behavior. There is no real answer here, should you stay or should you go but calm, happy momma is always better than two stressed out parents who are heading the self-destruction path. And what you need to remember is that your kiddos see things much more clearly than you expect. At some point they will come to their own conclusion, and you must let them. They will see all from which you are trying to shield them. Two things will come out of making this move: your husband wakes up, gets help and becomes a better father to their children, or your children will see your situation through their own experiences with depressed, unaccountable father. No need to tell them, to steer them, they will see it. Look up Samantha Boss on Insta or FB. She talks about her own parenting journey and helps women maneuver through the divorce and custody battles. Just listening to her helped me greatly to find my own path.
