These posts resonate so much! I have 4 half siblings, I grew up being led to believe their dad was also mine. He was incredibly emotionally, mentally and physically abusive towards only me (and my mother) and I could never understand why it was only me. Until one day at the age of about 12/13 I was looking for something and happened upon my birth certificate which had a different surname and birth fathers name on it. It was years before I found the courage to approach my mother with this information, she confirmed that I had a different father. Many years later I tracked my birth fathers family down, they're lovely.
My relationship with my mother was never amazing (since come to realise during counselling they she was also incredibly emotionally and physically abusive to me too) but it worsened after I'd tracked down my birth fathers family.
I rarely hear from her, she never rings, I gave up ringing years ago as my phone conversations were always about how my half siblings are, she was never interested in me. I used to go visit frequently (an almost 4 hr round trip or overnight stay) buy it got harder when I had my 2nd child as she didn't have enough room, I can't afford hotels, and both children are terribly car sick. So we stopped visiting, she's been over a handful of times since, it's now been several years since we last saw her, my youngest doesn't really even know who she is. It hurts to know she visits my half siblings frequently but can't make the same effort for me.
I've come to accept (with the help of counselling) that she's never going to be the mother I want and need. I'll never, ever forgive her for treating me the way she has, and never forget her telling me that she wishes I'd never been born and I ruined her life. 😪
Luckily, my MIL is amazing and everything I needed in a Mum. 🥰
