Backstory: My mother is a compulsive liar and a narcissist although as she is now elderly and my mother we still keep in contact. My mother and father split up years and years ago however before they split up I caught my dad having an affair which I kept to myself for a very long time but like all family secrets it came out eventually through someone else but I also agreed it had happened. My brother seems to have taken exception to this and every christmas/easter/birthday or anytime he has a few drinks he brings it up but calls me a liar and says it never happened. I am of the opinion that continuing to ask the same question and look for a different answer is a totally pointless thing to do but he does it. ALL THE TIME. Most recently xmas last year and then again my birthday in July. We have always talked about it when he is sober but I am tired of it and it came to a head last month and I begged my dad to come clean and stop making me out to be a liar and I was assured this had happened however when I asked my brother about it I got a load of abuse and was blocked on social media and his phone etc. Under current restrictions he lives too far from me to go to the house to contact him.
So today, my mother rings me with the great news that my brother and sister in law are going to have a baby. They have been trying for a long time and this would be the first other baby in the family bar mine. She says he rang her and stepdad second after contacting SIL family and then my father and apparently put it up on instagram after that. I got so upset that my brother or SIL did not have the decency to tell me themselves and that I had to find out through a third party today - most notably the woman who has pitted us against each other all of our lives (im her scapegoat child, he is her golden child) and my mother of course started a fight with me telling me I have no right to feel hurt or humiliated and that I need to just suck it up. My heart breaks in all this because I get on really well with SIL and aside from the drunken rants from my brother we are very close so I feel I am the last to know and that really does upset me. So - have I a right to be upset or not? I cannot help my emotions but I just want to know if I am being overly sensitive to the situation? For context when I had my child my brother was the first person I told - even before the childs father and my brother is my childs godfather too.
