Need advice for a WW who left Part 2

[Uphill]

I follow lots of threads but rarely post on any other than my own because I feel like I struggle to do what works in my own sitch. I don't want to try to give advice on top of that! Haha I did everything wrong also, seems like a common thing around here. I currently have a L working on custody papers for 50/50 right down the middle. I pay child care, S4's insurance and also her auto policy (title in my name also). On top of that I had been giving money to help as she was threatening child support. I even bought her groceries because she was broke. That is going to stop very soon. I got to thinking.... He uses all the same stuff at my house as he does hers. I pay all his expenses, clothes, shoes, insurance, copays, child care... Everything. All she has to do is make sure there is food on the table when he is there and I end up doing that also?!?! Wtf? I never sat back and looked at it but now that I have I feel like I'm getting raped!
