Texas child support laws, procedure to remove child support order

a selfish mother wanting to remove child support orders just to take away the fathers rights: My boyfriend and i have been wondering, how easy or complicated is it for the mother of his child to remove child suport orders from him. She is doing it all for the wrong reasons. She wants to take his rights a way now cause he is with me and she has done serveral things to try, she has called CPS on him filing for negelctful supervision and he just received a letter from then sayint he case was droppped cause there was no proof..she is lookin for anything an everything to keep his daughter away from him. she even had not let his dauther come with us on his weekend so we called the cops and all they could do was make an incident report. so is it possible for her to just go in and have them removed or is it a long process and is it even possible cause then all he would have to do is go and put himself back on child support right - Is this your question?
