My child's mother left the state of Indiana the last Sunday of June. My son was 3 at the time and is 4 now. I am still paying child support while she has been gone since June. I also have her biological son as well, a 5 year old. I have raised him since she was 4 months pregnant and consider him my child and want to know what I can do about getting custody of both of them and stopping my child support.
