Nick ... regardless if there is an OM or not ... it does not matter (Well the pain hurts like heck ... but not to get sidetracked here...) Thing is many LBS's ... myself included become obsessed with the OM, or the thought of one, it takes away from what you need to do.
As far as the W taking S 100% of the time, as a parent you have rights, do not allow her to use nor threaten that ... its boundary setting time in that area, she needs to know if she pushes through with this you will fight tooth and nail for your right as a parent for no less than 50%. The fantasy bubble she has in her head about what life will be like needs to be popped.
As far as moving ... nope. YOU stay, she wants this not you, if she stays ... great, but you do not go anywhere. Its a common question/issue here. You stay in the house, in your bed, in your bedroom, if she wants to move out, sleep on the couch, whatever thats on her ... you stay.
