I am feeling utterly bereft and need advice. Let me explain...
My daughter and I fell out several years ago over something really silly. She initially went to live with her paternal grandmother (who never liked me) and then with her father and his new wife. Despite my pleas she refused to come back home and it really broke my heart. Attempts to reconcile over the years, with the help of her brother, who is three years younger, never lasted. She really didn't want to have anything to do with me and would say "the time is not right". My friends and family would say that when she has children of her own she would get back in touch. So I clung to this like a drowning man clings to a life raft, despite my reservations that she may never have children because she had became anorexic when she went to live with her father and his wife.
In September 2012 her brother, who had been living overseas returned to the UK on a short business trip and he arranged for us to meet up with my daughter and her new partner for lunch. The lunch went well and at the end of it we exchanged telephone numbers and I really hoped that we could at last start to build bridges. She was, after all, 31 by this time. We exchanged text messages, despite the fact that it would take days for her to respond to my texts and my calls went unanswered. But I was patient. She was too busy to meet up before Christmas that year so we met after Christmas and exchanged gifts. We continued to text but it was taking her longer and longer to respond. She was also too busy to meet up for coffee/lunch. Then in August 2013 I received a text from her saying that she was getting married in October 2013 and that I was not being invited to the wedding as it was going to be a private affair with a handful of close friends. I felt extremely hurt. I know she has a right to invite who ever she wants to her wedding but it felt so callous to be told in that way. I felt as if I was being rejected by her all over again! I text her back and said she had really hurt me again and that I could not take it any more and said I would leave her alone to get on with her life.
However, although I said that I would leave my daughter alone I continued to seek updates on her life from my son who had remained in contact with her. My son and I have always been close and I thanked God that at least he had not turned his back on me. However, in August 2016, in a telephone conversation with my son he told me that my daughter had had a son who was nearly 12 months old. I couldn't believe what I was hearing at first and asked him to repeat it. Then it dawned on me that my son had kept this from me the whole time. All the video and telephone calls we had had and not once had he mentioned that she was pregnant or that she had given birth to a baby who was now nearly one. I asked him why he had not told me and he said that she had asked him not to tell me. I said but "I'm your mother, don't you think I would have liked to have known that my daughter had become a mother and that I had become a grandmother?" He messaged me a photograph of the baby and I was really grateful. I cried. I said I still couldn't believe that he had withheld this from me. This was such a significant event. My daughter had had a child. And suddenly I realised that if she hadn't reached out to me when she was pregnant and following the birth of her baby who was now nearly one, she never would! I became virtually hysterical at this point and demanded to know why he hadn't told me. I felt that he had betrayed me too. He said that she had told him that she would never speak to him again if he told me. I said but I'm your mother. His next words drove a steak through my heart "Do not make me choose between you and her!" He never sent me another photograph of the baby. And although I continue to ask how she is in every conversation I have with him he never tells me anything. Then four months ago he inadvertently told me that she was expecting another baby. I asked a million questions but his stock reply was "I don't know".
I went to stay with my son recently and we have spoken many times since my return but he let slip today that my daughter had given birth several weeks ago. I asked why he had not told me sooner. He said you know why! I again said "But I'm your mother. She is not going to know. I have no contact with her". I then asked him whether it was a boy or a girl. He hesitated and said "I think it's a girl. But I'm not discussing it any further". I am truly heart broken! I just can't believe that my son would not share this wonderful news with me even if I will never be able to see any of my grandchildren. I felt so hurt that I ended the telephone call. I feel really betrayed by my son and I feel that he has made his choice and chosen his sister. Am I wrong?
