Ramblings About Child Support

I received word that my June's child support came in on the last day of the month....I was sooooo sweating it --that I was not going to get any this month. Of course, it's July now and is barely going to be posting to my account. I don't understand why it's like pulling teeth to get a small amount of child support ON TIME! There have been so many other Dr. visits that I have had to cover, extra stuff for school, and just basic needs that he DOESN'T help with so why is it have to be one of those things that makes me want to just pull all his hair out? I have told him time and time again that the chiropractor visits are cash and not covered by insurance and that I need help and his reply is " at least SHE has insurance, I don't" And that's because he only thinks of himself. What a shame! Was this REALLY the man that I married all those years ago?
