I don't know all the facts (sorry for the lawyer talk) but it seems like you are very reasonable not wanting a child molester to be around your child.

Be aware that terminating his rights flat out might affect your child support (which would affect your child).

Although, if he goes to prison... there might not be that much child support coming.

Call a lawyer. They will be glad to give you a free consultation and discuss your case.

Good luck with everything. Sounds like a stressful situation for your whole family.
