I dont know if this will help you but my sister refused to speak to my mother years ago and when she fell pregnant she refused to let her see the baby.... and held out on this for about 2 years .... after that she conceded to let her see him and has started to do so more frequently.
Have hope because people soften with time. Dont lose faith and remember this isnt your fault.

I really feel for you, it must be awful, are you able to talk to him on the phone(if he's old enough to talk) How is your son coping with it all.

Hold on to your memories of your grandson, you've had a major role in his life and he needs you to keep going.

You never know what the future holds and he could need you again, I hope and pray that you will see him soon and on your part, all you can do for him now is be there waiting for him.

I'm so sorry you're suffering it must be hard.x

I am so sorry isolated. Does your state have a mediator process? It is much cheaper than dealing with lawyers, and might be another avenue for you until you find another lawyer.

There is no time limit on your grieving. No rule that says "okay, you've had this amount of time, now you have to stop."

I NED IT TO STOP, IT IS RUINING MY LIFE..MY LIFE HAS COME TO A STAND STILL, I CAN'T FOCUS, I FIND NO JOY IN THE PEOPLE OR THINGS I USED TO LOVE DOING AND BEING WITH...I FEEL HELPLESS AND PHYSICALLY ILL MY ANXIETY IS OFF THE CHARTS!

oh honey I'm sorry all this has happened to you but you must hold out hope that you will see him again. is there nothing you can do, no legal red tape that can enforce you seeing him more often?

I don't know the whole story, and as a grandmother, it would kill me heart and soul if for some reason my son in law got custody of my grandson and took him away. He wouldn't, he's a great guy towards me, but I can't even phantom this pain.

However, maybe your grandson needs some adjustment time to living with his mommie. Do you get to call him? Can you talk to him online, maybe with a computer camera? Za's father lives in Iraq and they visit by computer cam all the time. Or, invest in a good long distance plan, or cell phone with free calling on weekends.

Kids love everyone, they kinda take people as they come. And, feeling guilty about loving one more than the other or both is just unfair. They don't care about your mistakes, or the past, they just want everyone to be happy. And, they should not be made to take sides.

Perhaps you can talk to the mother, treat her as an equal, apoligize for any misconceptions on your part..(yeah, she may be at fault, but that is not the point,) you are trying to convey to her, that you are willing to put the childs best interest in front of adult pride.

Who knows, maybe grandma Santa could buy the grandson a computer camera for christmas?

Kids love mail, send him a card..whatever. Let her know you want to be a team player in helping to raise your grandson.......if that don't work, well, kick her ass..(lol) I am joking about the ass kick, but it's time to put difference aside and love your grandson.

Find an attorny and file an order to show cause the day after he is supposed to arrive for visitation at christmas. You can even do this on your own. That is stating that the court wants to know why she is in contempt.
I have been doing this for 13 years and it never goes away but you eventually get numb. My girls were taken away by their Law-enforcement father becaseu he is a Fed. Cop and the courts let him have the kids even though the evaluations said he would use them to control me. He has, I have not seen my own children in over a year because he is in contempt and the judge keeps saying every time we go in for an order to show cause that he needs to comply but he never does. THey would throw anyone else in jail but not a gold old Federal law enforcement officer.

Pray and act and think in Love and god will grant miracles.
Think of the love in your heart for your grandson and try not to focus on the pain.
Im here for you.
