The Start dynamic has nothing to do with the Relationship Story so you really can’t use that as a basis for determining whether or not the Relationship grows or decays. You can have a story with a Main Character Growth of Start with a Decaying relationship just as much as you can have a Main Character Growth of Stop with a Growing relationship.
The “something” or “someone” or “particular group” referred to in the gists can be substituted for whatever storytelling you want to apply. Because Dramatica can’t tell what your subject matter is or what your genre is (in the classic sense), the decision was made to keep the gists as general as possible.
I’m not sure how the two of them not having money but are too proud to let the other know would be anything to do with constantly examining oneself for something.
Let’s put it this way – Marybeth and Sebastian have known each for awhile now. Somewhere, not too long ago, one or the other got on the other’s nerves for constantly examining oneself for something–pock marks, validation for their efforts, etc. It keeps them from getting together and falling in love. OR it could be they’re both so busy locked in their own worlds searching for their own purpose that they ignore the other or don’t participate in what could be a very synergistic relationship.
Either way you need to address this as a PROBLEM between the two characters. You also have to show how this problem presents itself in the story. WHY is it a problem? Too many times people think they can just write “Marybeth and Sebastian constantly examine the hours that they slept the night before” and think that’s all they have to do for a story. It needs to create a PROBLEM. It needs to motivate some resolution.
