You're kidding right? Go back and read what you are writing. It sounds like you are already succumbing to the gaslighting that comes with this crap.
If he thinks more clearly with you not around, then let HIM leave. You won't be around but you get to stay in the house. If you leave, you are just placating and enabling.
The biggest mistake people make when DB'ing...and I made it too is they start feeding into the walk away spouses craziness. Agreeing with whatever they want. Boundries. If he needs to sort out his feelings away from you, then HE needs to own up to that and go do it.
Unless you are being abused, do not leave your house/bed/any other symbolic base of power
