Throwaway account being used. Also posted in https://www.reddit.com/r/TwoHotTakes/s/glvfxCH254 I invited my dad and stepmom over for Easter brunch to join myself, husband, and daughter. My dad decided to bring an additional guest without asking, and didn't outright tell me either. The text conversation this morning went: "Do you have a 10:30 mass time?"- Dad "Yeah, but we're not planning on going to mass." - Me "It would be myself and Beth. But don't know if she's coming. She was out late and not sure if she'll be up yet."- Dad ... this is the first mention of his intention to bring Beth, who is the intended additional guest. "I don't know Beth, she's not coming here."-me. "Not sure how to respond to that on Easter morning? I would never put you in any danger, she is polite and safe to be around. No drugs or bad behavior just a kid." - Dad NGL this response triggered me because her being a good kid or not being a good kid isn't the issue. I felt he was being manipulative by not just flat out asking when making the plan if she could join. I had no idea she'd be at their house for the holiday. I don't know her family situation or why she's not with her family. All I know is they live 1 state over. I also didn't like the emotion appeal of "it's easter" I don't care what day it is, you didn't communicate your intention or ask to being someone. This is where I may be the asshole, or could've responded better. My response was, "Sure, but you never asked. I don't know her, and she's not my family. You can't just bring a stranger to my house." My dad then said said, "Well now we have drama, I have Ben (step mom's son who i also didn't know was at his house) and Beth both up so I guess we will have to cancel unfortunately. Sorry for the Intrusion." Had this whole situation been approached differently, and communicated ahead of time, I would've responded differently. I didn't appreciate this being sprung on me the morning of, and he would've just shown up with her in tow, unannounced, if the conversation on mass times never happened. Beth is a college freshman, that my dad and stepmom have living with them for the past couple of months because they live close to her college. They know her through friends of my stepmom. I've never met Beth or her family. I'm not super close with my dad and step mom. They were married when I was an adult and out of the house, and I'm not close with her kids, there's a big age gap. We live almost 2 hours apart and see each other a few times a year. There's a lot of family history and past dramas of them not respecting my boundaries when they were watching my daughter (who is autistic): my dad and mom had a very messy divorce that Iwas put in the middle of: there was child abuse in my home growing up, and stuff so we have a pretty rocky past. My husband and I maintain low contact with my dad and are no contact with my mom if that's relevant. There's a history of my dad going above and beyond for others like this, while neglecting the needs of his own kids. (For example, I was completely and financially independent and paid for an apartment when I was 18, despite my college being 10 miles away from his house) It's hard to explain, and my parental trauma is something I'm working through in therapy, but it can hurt when you see your parents being performative for others while putting their own kids' needs or feelings last. That emotional baggage being what it is, and just trying to add context to my emotions. In summary, AITAH for saying Beth couldn't come over uninvited? EDIT: Wanted to add I messaged my 3 sisters (all in different states and therefore unable to be together today) about this and they all thought I was being mean for saying no to Beth coming which is what prompted me to post for some outside perspective.
