In a case like this, I'm not all that sure that anyone's feelings should be irrelevant. If (A) cares enough to think about breaking up for (B)'s benefit, then that says right there that those feelings are real and they matter. Of course, there's the possibility that (A) could fake things like that just as well as (B) could fake happiness. What's called for, to me, seems to be many long conversations, not this black and white, yes or no, stay or go. Life isn't lived in extremes like that. If (B) cares, they need to own up to their feelings, good or bad. If (A) cares, they need to open up these talks (even if nothing in their behavior changes right away) instead of making choices that could have them both unhappy.

I agree with Chi. If an honest opinion is asked for from someone acquainted with more than hypothetical, they should give it.

If I was (B), I would be doing what I could to find out what's causing the behavior. Giving up on people is not something I'm known for, even if I don't go out of my way to spend every second with them. But, I'm the first to admit that I'm a bit different from the norm. Until I know what's going on, breaking things off simply wouldn't be an option at all.
