Am I the selfish one?

My aunt is having her first child. She is pregnant and so far has only let her friends be involved in the pregnancy. Gender reveal, baby shower, it wouldn't surprise me if they are the ones at the hospital with her to. The only reason we even got invited to her gender reveal was because she knew my mom was upset, but she didn't even bother inviting her own parents. Now she's 22 and immature for her age, but we are her family. I feel like she should include us at least a little bit. The only time she is even around us is if she needs something. It's been that way since she was a kid. I feel like her boyfriend likes us more and they've been together for not even a year! She's known us her whole life! Now knowing myself I will probably never let her know about me being upset but is it even appropriate for me to say anything? After all this is her child and if she thinks it'll be more enjoyable with her friends that's her choice. I just don't want to mention to her that I'm upset and be turned into the bad guy, she gets very defensive. What would you guys do in my situatuon?
