You already closed your thread about child support when you didn't get the advice you wanted, now you try again, if you think we are so stupid, why ask at all.
Your boyfriend will have to petition the court for visitation and still owes the court ordered child support even if he had 10 more children. It is his own fault that he failed to appear and got supervised visitaiton, It's his fault he moved to TX, it's his fault if he makes less money. He is lucky he's not also paying for medical and child care expenses too. Now maybe you need to go out and get a job and help support the family you helped make, you knew all of this since his 1st child was 2 months old, and YOU chose to have two more children with him. Both of you need to grow up. If he owes back child support it doesn't go away because he doesn't visit his child and he cannot TPR to avoid child support expenses, you know all of this, so quit whinnnnninnnnnnnnnnggggggggg
