Good deal, Zew. VERY impressive use of this time that you have, and great work at detachment and getting all your ducks in a row.
It's all about the "SWOT" at this point -- Strengths, Weaknesses, Opportunities, Threats. You've done your homework and gotten good counsel as to what you can expect.
I think it's going to come down to whether or not you can manage the damage for the next 14 months. Provided your boundaries are MOSTLY respected, and the kids aren't being further harmed, you're probably wise in your waiting.
I just hope the wild card known as "Wayward Wife" will play nicely with others.
