CW, you know I know exactly how you feel. It is just awful to feel so powerless, so incredulous at what our Hs are doing. I worry a lot about how my Ds will be affected in school, too. D11 is going to a super-competitive school next year and it actually says in the literature something like "kids going through any other major changes in their lives, such as a divorce, will have a hard time keeping up."
Of course, just because it's written down doesn't mean it will happen, but given my D's temperament (highly sensitive and anxious), I suspect this is going to hit her hard. My H adores our Ds too, but he is clearly in denial about the effect the S will have on them. If he thought about it too much, he couldn't go through with it.
Are you sure you have to sell the house? Is there any way to rent a room or something to defray the mortgage cost? (I'm sure you've thought of those things already.) As you know, I am going to have to rent our third floor in order to stay in our house. It will mean that my bedroom will be a windowless space with very little privacy, but I love our house and our neighborhood and I refuse to sell it anytime soon.
I guess this is where the Ls come in. Fight for your house, dammit! We who are in this position of being given no real chance to save the M deserve something to compensate. I can totally understand why Ds can turn so ugly. It's very tempting to make our Hs pay for all this emotional agony in some way.
