I lived that life for many years. My fears of being "without him" were so irrational. What did I think I would lose by leaving him? As it turned out, I now have one less "child" to take care of. He wasn't a partner, he was a burden. It was so much harder being married to him than it is being a single parent. Being a mom is a joy now without all that resentment and anger dragging me down.
