AITA for not inviting my mom to my graduation?

Hi! I am a silent reader here in reddit, and maybe it's time to share my story. I (22F) recently graduated from college, and it’s a huge achievement for me. I’ve worked really hard, and I’m really proud of myself. I didn’t want a big celebration, but I decided to have a small gathering with my closest friends and a few family members to mark the occasion. I’ve always had a complicated relationship with my mom (50s). She’s not a bad person, but she’s been very critical of me growing up. She’s always had high expectations and never really celebrated my accomplishments. Even when I did well in school or achieved something, she’d downplay it or find something to criticize.

In high school, I got straight A’s, and she told me I could’ve done better. In college, when I made the dean’s list, she said, “Well, you had it easy, you didn’t have to work.” She’s always been like this, so I’ve learned to just do my best for myself, not to seek her approval. I’ve tried talking to her about how her behavior makes me feel, but she brushes it off or gets defensive, so I gave up a while ago.

When I was planning my graduation gathering, I didn’t initially think about inviting her. My dad (55M) and I are close, and I was excited to have him there, but I didn’t feel comfortable with the idea of inviting my mom. She’s never been supportive in the way I needed, and I didn’t want her presence to overshadow what was supposed to be a happy occasion for me. I knew if she came, she’d make some offhand comment about how I could’ve done better, and I didn’t want that negativity at my celebration.

I ended up not inviting her, and when I told her about the event, she was hurt. She said that it was a “huge mistake” and that I was being petty by not inviting her. She reminded me that she’s my mother and has been there for me in her own way. Now, she’s not speaking to me, and I’m feeling conflicted. I don’t think I made the wrong decision, but part of me feels guilty for hurting her feelings.

So, AITA for not inviting my mom to my graduation?
