Quacking is generally used as a form of manipulation.
So if you felt he was trying to manipulate your feelings, or manipulate you into doing something, then yes - it was probably quacking.
But if he wasn't trying to get you to do anything, feel any particular way for his benefit, or anything like then, then no, he wasn't quacking then.
Most of the things my XABF said were quacking, but not all of them.
When we got dressed up to go somewhere, for example, he'd get a dreamy look in his eyes and say how beautiful I looked, and how much he loved me. He didn't expect me to do anything, he wasn't fishing for a compliment, he just wanted to smile at me for awhile. Those comments were honest.
I don't have many memories of "non-quacking" comments like that, but the ones I do have mean a lot to me, and they're "enough".
I am sure you can find "enough" as well. Alcoholics are flawed, imperfect people, but every once in awhile someone beautiful can shine through, and those are the memories I hold dear.
