I think it's important not to let emotion cloud filing decisions and what you may accept as the cited reason. I wouldn't file if you don't want a D, don't accept any non valid reasons either just to be seen as being helpful, but do be co-operative where possible. If your H should file he may well expect you to fight/delay things. Being timely in replies rather than dragging things out will help create a co-operative feeling, and after all you're not going to get H back should he go through with filing by providing resistance there. Just my thoughts
