Why do some people ALWAYS SLIP THROUGH THE CRACKS...

It always seems to bother me how some people are meant to follow the rules, and others can simply play by their rules and ALWAYS GET AWAY WITH IT. All of my life I have always played by the rules always doing the right thing. Never taking to many chances always being the responsible, practical one. Always putting the family, bills, job, first. So why does it seem that he can still only play by his rules and there are no consequences for him AT ALL!!!! I FOLLOWED ALL THE RULES AND DID EVERYTHING MY LAWYER, MY FAMILY, MY FRIENDS, AND MY GOD TOLD ME I NEEDED TO DO FOR MY FUTURE AND FOR THE KIDS. I filed for Divorce had him served got him in front of the Judge and even called Child Support Enforcement today to let them know he was already 3,000.00 behind.
Thinking that now he will get his there is no way they can let him get away with this. I mean every choice I make has a consequence, if I do this I can't do that. If I go out to the movies that's $40.00 that could be used for food or gas to get to work ect... Yet he can be $3.000.00 behind and tell me " I will pay you what I can when I can" and this is ok with everybody. He can go to Nascar races at $200.00 a pop instead of paying me my support. HOW IS THIS RIGHT IN ANY WAY???? He can just keep doing this to me for as long as he wants to and I have to go on the hope that SOME DAY THEY WILL CATCH UP WITH HIM. What the hell good is child support going to do me when Austin goes off to college.  Who cares if he won't be able to buy a house in another 10 years HE NEEDS TO BE HELD ACCOUNTABLE NOW!!!!!
I just feel like all the Legal stuff I went through all the appointments and time missed from work was ALL FOR NOTHING!!!!! It's like he keeps walking out on me over and over again. With that condesending attitude " See I can do what I want and there is nothing you can do about it" This just makes my skin boil I have always taken the high road and been the better person and i'm thinking maybe I need to start being more nasty and mean. I mean like they say " Sometimes being a BITCH is all a woman has to hang on to" I'm tired of always being the sweet cool headed one who always forgives and always cares. I FEEL LIKE A FREAKING DOOR MAT!!! If I want to get him in front of the Judge again it's going to cost me more time and money and there is no guarantee he is going to pay even then so what's the freaking point. I FEEL TOTALLY DEFEATED RIGHT NOW..... At the end of the day the court orders for child support and spousal maintanence, the hours of Attorney fees, and thousands I lost in missed work hours didn't amount to squat... So now what??????
