OK well first of all man up and quit letting her push you around. Move back into the house, it is just as much yours as hers. DO NOT allow her to remove you from the business. Again it's just as much yours as hers. You need to protect yourself first and foremost. You have just as much right to the home, the business and access to the kids as she does and don't let her convince you otherwise. If she starts throwing threats around then hire a lawyer. Too many LBS's get BD'd and then move out and give their wife everything they ask for. Guess how much advantage it gives them? NONE. She already has very little respect you and if you let her treat you like this then she will have even less. Take control of your life. She will hate it, but inside a bloom of respect will have started and will build over time. Without respect you will NEVER have a relationship with her again, it's your only path to future recon.
