Learning as I go

[tested metal]

I need some feedback regarding this whole divorce process and my wants.

W filed and want full custody of D. She claims that then she will share 50/50 custody and child support. In this state 90/10 custody is the only accepted legal terms and then parents can work it out otherwise.

The problem is I don't trust my W. I want full custody and would share 50/50 and child support. The difference is I know that I will give her her half of child support back. I am pretty sure she won't.

Is this reasonable? Does this sound controlling? I want to be fair. I also want what is best for my interests but overall what is best for D's interest.

If W gets full custody and does not pay back 1/2 of child support, I might as well give up my 50/50 that she offers because i will not be able to afford it and will not have time to be with D because I will have to work more to pay child support.

Then she will use that against me saying that I must not care about D, because I won't spend time with her. She is that passive aggressive.

Any thoughts? I just want to protect myself and need advice from the experienced people.

Thanks!
