Our twelve yr old lives with me full time. Not once has he spent the night with his mother in all the 24 months she has been gone. Our three yr old stays with me for seven days every other week. She has had a baby by her new live in boyfriend. I do not pay her child support for our three yr old as I have him every other week and buy him clothes and the necessary things needed for him. On the other hand I do not get one dime for our oldest son from her. She feels where she has the new baby that it would negate her from paying me support for our oldest son. I feel she is still responsible for him as any of our children. I worry that where I make more money than she does that if I push support I will wind up paying her for our three yr old. Any money that comes out of my budget affects my twelve yr old and I do not want to take from him (Clothes, tutoring, necessary things he needs). I make around 30000 a yr and she makes around 17000 a yr. Am I biting my nose off to spite my face or would it be advantageous for me to seek support??
