child support

I havent got child support in 5 months, I thought for sure tht they ( family court) would have filed a warrant for his arrest by now.  So now in order to get child support so I can get my kids winter coats!! I have to go to court, I really dont think I should have to go thru this!! I know he told me tht he wouldnt be there for us if I left but really he wanted to have two kids! He should help support them. I think tht this system is wrong.  How do they decide tht a warrant should be granted especially when so much time as pasted.. I have met single fathers and they all can not go a week without seeing their kids.  my anger has gone away alot bc I dont have to deal with all his bull anymore or his gfs, and honestly tht was a big reason I stayed for so long I thought I had more control over what happened around my kids and I figured if we were not together then they would be around everything I didnt believe it.....
