I think that people have different levels of tolerance and capacity for love, hurt, anger, etc.
Your W can work extremely long hours and the stress that comes with that but can't deal with the stress of the relationship.
Her friend on the other hand seems to have a capacity for managing BS and still manages to keep it together.
If there is a bright spot regarding W's friend visiting, it may come in the form of a realization from your W that crap! If my friend can hold things together through thick and thin, then maybe I can too?
Wishing you all the best!
