The journey begins

I do not like the fact that in their offer STBXW is getting to include all of the debts that she’s run up since we split up and I’m stuck with submitting just the debts we had when I moved out.

This is not telling him what you want, it's whining about it not being fair. Tell him exactly what you want.

"L, I do not accept responsibility for the debt that STBXW has racked up since we separated and I will not paying half of that."

To the point. Clearly stated.
