I have only this one chance to respond as I am busy today and will be quite busy for the rest of this weekend. Long weekend busienss project. At least is a promotional / social activity.
Best response to your H might be: "Sorry you feel I'm ignoring you as that is not the case. I am available (insert time)."
Look, the reality is he DOES think you are ignoring him so he's telling you how he feels. If you respond back suggesting he's making assumptions, all you are doing is attacking him back.
If you feel you MUST say something else, do keep it short.
I will not be available after this post and not sure when I will be back this weekend, so I won't be able to respond if you ask for clarification or options. The above is all I can provide at this time.
