I (25f) and my sister (28f) are best friends. We do everything together and I love her with my whole heart… That being said, she has this asshole of a partner (27m) that I’m now going to be stuck seeing for the rest of my life even if i don’t want to??
For context; They were together for 10+ years at this point and about a year ago (let’s call him X) X and sister were living at my parents house and life was good they were looking into buying their own house. X took some weekend trips here and there to see “friends” “family” or whatever. Turns out he had been cheating on sister for at least a few weeks. she saw messages on his ipad of all things. It was devastating to our family, what he did to her blindsided us all. he continued to lie to her after she confronted him, said he was going back home to be with family and think about what he had done but he was actually visiting the girl he was cheating with. he had lied about multiple different things throughout their relationship that we just brushed off or quickly forgave him for but now looking back it’s all red flags.
Here’s the current issue: they have gotten back together over the past 10 months and she is now 6 months pregnant. first grandchild in the family makes people pretty excited and forgetful but knowing what i know about him and his actions, it’s making it hard for me to get to a place where i can be around him. my parents, grandparents, and younger sister (the only ones who know what he did) are really excited and don’t seem to be as upset and affected by what he did at this point. now i understand everyone moves on and forgive and forget or whatever but like no one is upset. no one, it seems like it’s only me. his morals and values do not align with mine and i fear i will never be able to believe a word that comes out of his mouth. my mom wants me to be involved with party planning and be happy for my sister and i am, i just don’t understand why i need to be involved. my sister gets frustrated with me asking me why im so upset and what makes me so angry about it and if she can be okay with it, why can’t i? and im sick of the questions and the pushing to forgive and to get over it. It comes off to my family as rude and immature when i walk away from conversations about it and when i shut down and go silent. i can’t win in the position im in even if im just trying to protect my peace.
To top it all off, my ex of 5 years cheated on me last July while I was coming to terms with everything, which has made forgiveness that much harder.
So AITAH?
