You asking that question just put two and two together for me (along it's just a hunch) ... Tammi's ex husband got custody of their kids, they lived in Louisiana. One of Tammi's pages (I think myspace maybe) explains this as "he was turning them against me" (more or less a direct quote - I don't have the link). I'm not sure if there was more there (and she is writing a book, oy vey!) or not, but it sounds like she's claiming she willingly gave in to let him have custody - that just might NOT be the case.
Yes that background info she was sharing on the internet was quite interesting. Something tells me that TPS tells this story every chance she can get. She's getting ready to publish it in a book apparently. And since she's got a connection to San Antonio and admits to having been there to receive at least one of her "certifications", I would imagine she's told lots of people there about her sad story. And just maybe she met people who told her about that "underground" network for abused women who feared losing custody of their children?
