This is wonderful! The thought of an examination of a relationship via their art before, during, and after? Brilliant. Putting it into a roleplaying game? I'm jealous of that sort of idea crafting; well done.
Very thoroughly fleshed-out (no pun intended) rules & instructions. This sounds like something that my wife and I might really enjoy, it's rare for me to find a game/activity like this that I think she'd dig. We were together early in our lives, and then kind of went through this and reunited 15 years later. Thanks for sharing, I'll make sure to let you know how it goes if we play it. :)
