So STBXW found the card in the bin when taking some cardboard out. She fished it out, and as luck would have it, I was literally out the door with baby for a walk. She asked me if I read it. I said yes. She threw it on the ground and walked away.
Now I feel terrible. I feel she needs an explanation. In some sense, because I have been distant in our M, DBing feels like more of the same. I recall it worked with BD1, but with BD2, it certainly is not.
