A mate of mine was so financially crippled from child support, he was literally working to pay his ex. It was ridiculous. Sadly he took the wrong option and started stealing from his workplace, a little every day, to top up his money. His workplace realised what was happening and monitored it for a couple of months. In the end, they presented the evidence to him, and he held his hands up. He'd taken about £3000. It was a terrible idea, but in his mind it was his only way out. Naturally he left his job.
News like this actually puts me off wanting children a little bit - it certainly makes you think twice and question whether the person you're with is the right one...
