My child lives with his father. We have joint custody. My child support payments are extremely high. I pay the normal amount plus arrears plus a very high medical insurance premium reimbursement to my ex-husband. This total puts me well over what a can afford to live. My ex-husband said that if I give up my rights and let his new wife adopt him then he will make it so that I don't have to pay child support or any arrears. Is this possible in the state of Texas? Please help.
