Can I just say that i think it's so great that you're family is having your T come and talk to them all. I don't know much about you or your situation, but when my parents separated (2 years ago) I look back and wish that we had of had some sort of guided plan on how to handle everything. My family was all over the map so to speak, and i think you are really doing the right thing - for yourself, and for your children.
I'm glad things went well for you
