We've been married 3 years, she has never worked(even for the last 10 years before we met). She recently kicked me out of our house and kept the car. Two days later I discovered she has a new boyfriend. Now I'm living with a friend and have to find rides to work and back, and she recently asked me when I was filing my taxes so she could get half. We have one child together and I have supported the baby and her all last year. Do I HAVE to give her any of my tax refund?
