I will try to keep this as short as I can.
In May of this year I found out some things about my childhood that my mother had lied to me about, such as where my dad was buried, siblings that I didn't know about, that sort of thing. I also found out that my parents were not married (even though she had told me that they were) and that she had re-registered my birth 4.5 years after I was born to change my name. I only found out all of this because I ordered my birth certificate because I am due to get married next year. I did have a short form birth certificate but I had mislaid it. I am now 40 years old and my dad died when I was 13. I was told that he was cremated but in fact he is buried in Ireland. I did not know this until very recently.
She refused point blank to discuss any of this and basically has ignored me and acted like the injured party since.
Anyway my son (10yo) goes to stay with my mother every summer holiday for six weeks. He loves it. This year she made it very difficult for me to talk to him while he was there and would not tell me what flight home he was on (she was coming back with him, he wasn't on his own). She just said that she would text me when they were back in the country and I could collect him from wherever she was staying, but she wouldn't tell me where this was in advance.
She then contacted my son's dad (who was very, very violent when we were married - the police installed a panic button in my house when we split up) and arranged for him to collect my son from the airport. My ex and I split when my DS was 18 months old. He sees his son every Wednesday and every other Friday night. He was a horrendous husband but a reasonable (if a bit uninvolved father).
I was a bit
about this but there was nothing that I could do about it after the event.
Anyway she now phones my son at his childminders (who is also my best friend) and at his dad's house as she has told me that our relationship will never be 'normal' and she just wants a relationship with my DS. She also said that my exh has told her that she can see my DS at her house. She said that she will see my DS whenever she likes and sees no reason to communicate with me about it.
My DS loves his grandma and I don't want to affect that. However I am massively pissed off with her on many levels. She has undermined me with my son since he was born in many ways but I have let it all go because my son loves her. However the fact that she is now colluding with my exh over contact with my DS is, to me, out of order. She knows full well what he put me through and we have very little to do with each other, other than handovers when he returns DS.
Do any of you think that my mother's behaviour is normal and am I unreasonable in being upset with the way that she is?
