I am the father in this situation, and to shed a little more light:
My son and I have an awesome relationship. He also very much enjoys the relationship he has with caligirl, my wife. He lives far away, so he visits on his vacation time from school. He knows that we don't go to the meetings.
Problem is that I don't want to cause too much stress on him, for his mother says horrible things about me, though he knows this is not true. She is one of those witnesses that is much worse than almost any "worldly " person. If he were to see us celebrating a holiday, or something, I fear it will cause emotional stress on him, because as much as he loves it with me, she says how I will be destroyed when the end comes, and how I am displeasing Jehovah.
She gets things out of him with threats. She wants to know everything that is going on in my life.
The other problem, is that I have a very dear friend, that knows that I don't go to the meetings, but we have not discussed it further. I am afraid that he will not listen to what I have found out, and I will lose that friendship. I feel that time is all that is needed for him to see the light too. My ex will hunt his number down, and notify him, just to get at me. She will seek and find all elders involved before, tell them where I can be found, and what I do. With what she feels would be concrete evidence, she will not stop until she gets me df'd. She is very vindictive and hateful. Once that happens, then she will work on my son mentally about how he cannot see me in good concience.
She cannot do anything for several more years legally with visitation and all, but she will cause much heartache and trauma in our life that we just don't need.
I usually am the type where I am strong in my decisions. This one is so much more difficult. So many things on the line here.
