How can I make my crush realize he messed up by not inviting me to his Halloween party?

Basically to understand this post, you need to read the previous one, but my crush hasn’t invited me to his Halloween party. One of my friends asked me today if I was going to the party this weekend and I said “I didn’t know when it was happening cuz I wasn’t invited” and she looked at me and was surprised I wasn’t invited. What do I do to make him go “shit I messed up with her”

Update about this,

I finally talked to him and told him I was upset and he told me that basically, yes my ex best friend told him to not invite me. I called him out on it and he told me he regretted not having me there and said “I would rather hangout with you than with any of them at the party.”
Sooo now I feel like we have reached a new point in our friendship, but I’m just wondering whether he’s going to make a move. I’m also worried whether he’s gonna keep doing what she tells him to do.
