Ex's Go Away!

I hate when people try to talk to me like I have no clue what is going on. I am not an infant. I will not just accept whatever I am told. I do know a lot more than some people think. Why is it so hard for people to tell the truth? My ex-wife must have some mental disability or something seriously wrong with her. She lies about everything even the things that are not important at all. In fact if she would tell the truth it would actually be less harmful for all of the parties involved in just about every situation she has lied in. The most recent lies that are irritating me the most is about child support. She has made many, many attempts to raise the child support (even when I was already paying $880/month). I have talked to the child support offices many times and every time it is the same answer. I am told that she has made all of these requests and I am unable to file for reduction because she has a constant stream of requests filed. According to the child support offices I am unable to file a request for reduction until the other requests are dealt with. I really don't understand why she is doing this because the child support I have to pay doesn't even go to her or my children. The money I pay goes to the state because she has been on welfare for as long as I can remember now. The constant filing will not make a difference because of my income level but what really pisses me off is that she talks to me like I am an idiot!
