First its not a good idea to piggyback your question on someone else's. This can lead to confusion. You should start a new thread. So I've moved your question to its own thread.

I would suggest reading this sticky note:

You will not get his rights terminated except as noted in that sticky note. If he's not exercising his rights, why is it important to terminate them.

Merely not seeing the child is not enough to take rights away. Have you been taking him back to court for child support
