I think it’s normal to compile lists like that. For sure it’s a sign of a relationship on the rocks. It’s a form of journaling and therapy as well as something to look at and analyze. It’s most likely used when the other person won’t discuss so the only alternative is to write for oneself.
Definitely the sign of someone who’s stuck in a marriage
