I found out that after the last IRA transfer that I still owe XW $6000. I offered her $4800 which accounts for a 20% tax discount. She is confused about the tax discount and I am sure her lawyer will say that is fair.
Also, XW sent me an email last night asking to meet so as to discuss the financial of the kids extracurriculars. So we met today, and after a tiring 2 hour talk that got off topic a lot, she agreed to pay for S8's piano and any increase (about $100) to D6's violin.
