I'd consider dropping the MC if I were you. Every week it puts the focus on what she now considers a failed marriage. It reinforces in her mind why she needs to end it.
MC engages you in relationship talks and 'trying to convince' mode. Two things that oppose DB principles.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
