Edit: For reference, my sister’s mom is my dad’s ex-wife. He currently is partnered and lives with MY mom if it helps. My mom has generally been ok with the ex-wife but she shares my same sentiment in this situation and is equally annoyed that my dad didn’t tell HER that he had invited ex-wife. Sister has been trying to get ex-wife to see dad due to his medical issues and her pushiness combined with our dad’s most recent lack of communication about when ex-wife was coming over to the house to visit has caused my mom recent discomfort in regards to ex-wife’s presence. This might cause a bigger issue than I originally thought.

Hello,

First time posting to this community. I’m graduating in a week or so and wanted my friends & family to attend the graduation ceremony (I don’t want to walk but I don’t want my family to miss out on seeing me cross the stage). Anyway, grads at my school get six free tickets and I wanted to invite a good friend of mine who said she wanted to see me walk the stage.We talked about it beforehand.

I was going to give the last ticket to her but I forgot I had a family member coming to town (Whom I really didn’t care if they came or not but they are my mother’s sibling and mother insisted they not be left out) so I told my friend that I was going to give the ticket to my family member. She was okay with this and said that she just wanted to be invited to the after party (love her!!!).

Well, my school emailed us and said grads could claim up to three extra tickets. I gave two to another friend of mine who needed them and kept one that i was intending on sending my friend so she could still come. Then my older sister (half-sister w/same dad & diff moms) calls me one day and says that our dad invited her mother (his ex-wife). to my graduation ceremony. I was a little irritated because my dad does things like that without communicating with me and it was irritating because the decision to invite people is up to me as I had access to a number of limited tickets.

My older sister said she didn’t know that our dad had not communicated with me that he invited someone without my permission (like I said, he rarely does). She was a little flustered, because I sounded irritated, and said that she didn’t want to make a big deal about it but I told her it was fine. Felt a little awkward to say no at that point.

I’m still peeved though. I do not dislike my dad’s ex-wife but my graduation ceremony is a culmination of my hard work and I want the people who have been present and encouraging me down the line at every step of the way to watch me walk the stage. I’m not close to my dad’s ex-wife and I don’t understand why she needs to be there. I would rather have my dear friend. I understand I’m being unrealistic and immature over a minor issue, but I’d like your opinion. Am I the asshole in this situation?

Tl:dr Got one extra grad ticket I was gonna give to my friend but my half-sister sister said our dad invited her mom to my ceremony. I didn’t want to say no to avoid any awkwardness but I’m a little irritated by the situation.
