I am engaged to my fiancé, he has a daughter 15, and a son 16. He was married for 5 years, she cheated on him with his best friend and they tried to work it out for a year before they divorced but, she cheated on him again. He filed for divorce, they have shared custody of their 2 kids. His son lives with us 98% of the time, we take care of all his needs and wants (financially) which has becom difficult because he pays $800 in child support a month and his sons phone, car insurance and everything.
