Lifee, so sorry that you find yourself here. There a lot of people here who have been where you have and you will find a lot of support here.
My H no longer lives at home, but DB'ing is still possible. Just apply the concepts when the opportunity presents itself. My H is still in MLC land, but I can say that they do notice!
I too receive "the bomb" on a regular basis. I've come to think that the "speech" (what I call it) is more for them than us - an attempt to push us away.
I didn't totally get it in the beginning and thought I was doing it when I really wasn't, but Cadet is right ... detach, detach, detach. Focus on you. The time you have now is truly a gift.
