Me and my dad have never really had much of a real relationship. My parents split when I was around 7 and I'd go to his on weekends. The weekends became every other weekend, then once a month or not at all. He'd always promise he would come and see me and I'd sit at the window waiting for him and he wouldn't come. One weekend, I was finally staying at his and I was so happy, he then tells me that he's leaving (he moved from England to Wales). He left because he got another woman pregnant whilst he was still with my mom, and then a few weeks after he left, my sibling was born.
My mother and I started to visit some relatives on her side as she had been told one of her elderly relatives was terminally ill. After the terminally ill relative passed away, we continued to make trips to see the family during easter holidays, christmas etc. I began to experience CSA (my "cousin", he is 4 years older than me). It took me a while before I told my mom, she was in bits.
My mom called my dad to tell him what happened and he never called to ask about me and didn't come back to see me.
Anyway, a couple of years ago me and my dad were having a conversation in the car and I asked him "why did you not come back when that was happening to me?" and he told me "you just weren't my priority at the time".
This eats me up inside and sometimes makes me feel worthless. But I also feel like I should get over it as the conversation was a couple of years ago, on the other hand, I wasn't important enough to him, during one of the most traumatising moments in my life, after he had just walked out on us too. I just don't know how to move forward from this and I feel that it's silly and unreasonable to still be thinking about it.
