Bit of background:
NC with my father due to him being a selfish arse. My parents have gone are going through an acrimonious divorce that has lasted 15 years and still my father decided to sue my mother last year.
Reason for the divorce was my father cheating on my mother with an absolute horror of a woman. Fairytale witch style horror. After a couple of years, this woman was replaced with his current partner, with whom my father has two kids.
My father got married to this woman last year, inviting neither me (fine, as we are NC) or any of my other "full" siblings (who he does speak to). My two half-siblings were allowed to be present funnily enough.
There's no love lost between this new partner and myself, however...
Yesterday I found out that there's a rumour going around that my father is cheating on his partner. I know it's a rumour, but the person who has relayed this is trustworthy and not known for making things up. I have no doubt in my mind that this is true, he has form for it and it has come out after my parents' divorce that he had cheated more often.
Even though I am no longer part of my father's life, I am still feeling absolutely devastated. I feel so incredibly sad about this. It's a classic case of my father being selfish again.
I foresee history repeating itself, but this time with my two half-siblings being affected by it. That is if his wife finds out and if she decides to kick him out (and I would bloody well hope so!).
I feel my life is going to be shaken up again by the selfish actions of my father and I have just so had enough of it all. I know my siblings will be so sad.
AIBU to hate my father and wish for a different one? 
I am so jealous of my husband for having a nice, drama-free family.
