Hi Michekka, and welcome to the forums. First off, let me say that there are alot of people here going through tough times and who can relate to you at some level or another. After reading your post, my only advice to you would be to move on. I know it can be scary, and I know you can be scared that things will be exactly the same.
But you have to make a serious choice, and not for yourself. This choice includes your children. Your children will pick up on the vibration that you and you husband are not happy. And that will eat your children up like a cancer. If you feel that your relationship with your husband is going nowhere, and there's no repairing it, then you MUST move on for the sake of your kids. Otherwise, the tension is going to get worse and worse in that house, and those vibrations will seep into your kids and screw up their lives. They will start to see their parents behavior as normal, and then implement it into their own lives and the relationships they have.
Better for you to bail out now, while you can. It may be rough at first, even scary and petrifying, but there's a simple philosophy to keep in mind. "A single happy parent is better than two miserable parents."
I wish you the best of luck, and hope you find the clarity and courage to make the best decisions.
