Yes blob, hence the lines:
1) "Doomed to crumble unless we grow, and strengthen our
Communication. " - The less communication there is between the two, the better the chances are it will fizzle out with time, unless you fall under the school of thought that absence makes the heart grow fonder. If they continue to see each other and act in the same matter that brought them to this place in the first place, then of course the feelings will head in another direction.
2)"Cold silence has a tendency to atrophy any sense of compassion" - knowing their union would be wrong, they resort to the aforementioned silence, so that they can "escape from each other" as you so succinctly put it. Whether any of these tactics will work remains to be seen.
Oh btw fixed the 2nd to last line, Maynard does not say 'brothers, ' but 'lovers' twice. Though the prior would offer a bizarre and interesting twist to the story, like a brother stealing the heart of his brother's woman, or g** incest yuk! Lol.
