Please don't think that the children have to wear designer clothing, or your child support is supposed to immediately be used to take the children shopping for their desires... the child support money is needed to assist with utilities, gas, food, rent/mortgage, insurance, medical costs (which are HUGE) and many other issues, like school lunches and all the enormous school fees constantly barraged at parents.
My ex-husband has instilled in my children's brains that the child support is for THEM, to go get what they need and want, and not for me to spend on anything else. Now they are teenagers and I refuse to just hand over my child support (which I am just getting again after he's now $60,000 in arrears) so my daughters can go get nicer cell phones, Ambercrombie & Fitch and Hollister clothes and shoes, shoes, shoes b/c they are "cute and I need them". They have the mindset that their "wants" are "needs" when it comes to money their daddy sends, because he's brainwashed them as I am the enemy to drive a wedge in between us.
I'm not saying you did or do this, but child support all those years I didn't get it.... well, my parents had to help me with diapers, formula, clothing, food, transportation, utilities to keep from getting shut off. I lost a car to repossession once and then subsequently lost my job and home because he wasn't paying child support and I just couldn't make it. Think about your children's needs, and not the extras life gives. Being divorced - well, there's suffering involved if you had children (they without the two parents at home) and the CP struggling to meet all the financial and emotional needs of a single parent home. It's not easy by any means, and I made pretty decent money for a young single mother, it still wasn't easy, especially with childcare added to the mix.
