I have 3 kids by a female I've known for over five years. She has collected welfare for the whole time she has had kids. the thing is that, I've lived with her for majority of our relationship and she has told welfare in Kansas that I wasn't around. Now, since I've left the relationship she's moved a nother man in the house and hasn't told welfare of him being there either. he has been there since I left. I worked while I lived with her and proveded for my children and since then we had joint custody and welfare don't know it but she still collect welfare with her boyfriend staying with her and me still providing with my kids.she's lied to them saying I was no where around when in fact I was living with her. I didn't know anything about her lying to them untill they came to me for child support. Is this fruad and what should I do because I have two other kids to prvide for and child support takes my money to where I can't even pay bills.
