It is known that the relationship between Penelope and Odysseus is mutual and strong, the idea of them being aloof is a tad weird, however, I see your point in a case...
Sure it can be assumed that Penelope did lose hope for an act or two but she regains the hope that her beloved husband is still alive. :)
This book was one of my most favorite books that I've read in class with my peers, it's a quick read but it always keeps you interested in what will happen next.
