Sorry your PMA is in the toilet. Seems to be catching .
Lots of us here in piecing (it seems to me) are having trouble with feeling like we're giving our all, and getting not quite enough in return. Sigh.
I agree with (?) above, try not to attach your PMA to hers. It's really hard, I know. Especially when you get "called" on behaviours that seemed to be just fine a week ago!
And about bringing up the A and such bringing your W down, well, so what. It's not like a constant barrage is it? I'm mentioning things less and less, but only because I don't have any questions at the time. Not because of what it will do to my H's mood. It always brings him down. I just hsve to learn to let him deal with it.
Perhaps backing off a bit might be good in your sitch. If W notices and says something...hmmmm....maybe agree with her that you both need space and other interests?
Tough though, when work etc. is eating up a lot of your time. Quite a bind, J, perhaps this "dip" is just a thang and will swing back up to where you were a couple of weeks ago.
