Greetings. First, a child support action is different from a custody action. If you only have a child support ORDER, then yes, she can still file an action for custodial/visitation rights.
He will not be able to terminate his rights unless you allow him to do so. His willingness to “lose” his child should be noted.
I would ignore the grandmother, and just try to promote a healthy visitation with your child. Offer to bring her by once every other month. Make grandma have no reason for her behavior, which will only prove you the better person again and again. It is unlikely that if your ex cannot pay child support that his mother is going to retain an attorney and try to get any rights.
You will smell like roses - even if you are dating someone (as long as they are above the legal age limit [:)][:D][:)])
