In addition to all the rest of this, the LW's last two sentences are really something. "I can't spend money on my thirteen-year-old daughter because she's such a delinquent that I have to save for a lawyer" does not make you sound like a worried and responsible parent; it makes you sound like a jerk. Especially for such out-of-control behavior as--by the LW's own description--"not doing well at school" and "not wanting to attend family functions with her father". If he gave this excuse to his ex-wife, I'm not surprised she's not feeling in a charitable mood.
