Nap dodger, I am so glad you got that special time with your grandmother. Whatever your mothers relationship with her mother it was wrong to impose her views on you, but it is all about control, we are all different and no saints, but not bad either and should accept warts and all our family. Thankfully you got a chance to find that out.
I wrote down after one tirade, the things wrong with me that caused such bitterness, they amounted to, I got on her nerves, I was so apologetic, I made snide remarks, but when asked what, she couldn't think of one, then told it was a personality clash and she preferred her friends. For that I was ostracised, I agree I did apologise for what I didn't know what, because I wanted things to be on track and part of the family and see my gd, but she wanted no contact despite it all. To everyone whose child has estranged themselves look at the reasons they give when they have sounded off, I bet there isn't anything there that justifies it, for some reason they just want the relationship to finish. You can't fight it. I worry Celebregran that this counselling you are having doesn't make you rake everything over and you question all you did or said that might have led to the estrangement. If things were wrong, she should have talked to you, looked at what you and her dad did every day showing you loved her, unless she has been controlled by her husband and brainwashed, if that is the case again there is nothing on earth you can do as she will believe everything he wants her to. As parents we want to make everything right and our children to be happy, I had to just accept me being in her life didn't make her happy and after a long painful journey make the break. It will never stop hurting, but I have made a different life and at times almost forget about it for a while.
Rosy, I feel your pain, your son is in a very difficult position,eventually he will resent his wife and things will change. How can he ever respect and love her?
