It's uncomfortable because it's the opposite: the opposite of what your emotions are telling you ("Stay close, I love her"), and the opposite of what your rational mind is telling you to do ("Don't be distant like you used to be").
Both of those things no longer apply after BD. New game, new rules.
It's counterintuitive. Also scary, unpleasant, lonely at first. Then (2 months later, in my case) you start to feel more and more detached. Her tricks and bait and temp checks don't pull you in as much. You're not faced every day with reminders of what she did or is still doing. You feel more confident about your ability to be "fine either way." And she gets some serious time and space, not just the pretend kind.
In the end you get better at GAL and detachment. She gets a chance to miss you. You build your confidence and hope for the future. Everyone wins. For me, it's something that HAD to happen, or else I would have kept on digging the hole.
So no, it won't improve much, at least not overtly, or not in ways that are immediately obvious. But it will help YOU and in the long run, when YOU feel better, that's one more reason why W might look back.
