Father and grandmother rights
My son is divorced, has one son. His ex wife is remarried, with 2 small girls. It was agreed that I would have my son's visitations while he was away in Afhganistan. She did not follow through. Now my son is returning and she will not let my son and grandson reunite. Claims he has plans with friends. My son has ALWAYS paid child support, and a lot, if she said "jump" he would ask "how high?" just to see his son. He is 13. She claims his grades are not good, so he has to stay and study.
How hard and expensive is it to fight for my rights as a grandmother, and he deserves to spend time with his son, and he will fall off the earth for him. His dad would love to have him full time. The son claims he would like to live with his dad, not the mom. What can we do?
