Tax year 2021 was the one and only tax year in which a parent could claim a child on a tax return and get the child tax credit even if they had no income from working---so it sounds like your "ex" exploited that. However, if you were the one who was working and supporting the child, then you were the parent who could claim the child as a dependent. Filing your own 2021 return claiming the child was the "okay" thing to do; eventually the IRS will process the return and you should be the one who receives the child-related credits for claiming your son. Your "ex"-- who filed improperly and should not have claimed the child, will face repayment of the credit he received and may face penalties as well. Your BF likely received at least $3000 when he claimed your child.
