Friend didn’t invite me to wedding.

Hi, a friend that I admittedly don’t see very often, but do keep in touch with, didn’t invite me to her wedding. I learned about it from another mutual friend and was surprised that I didn’t receive an invitation because I didn’t think we had a falling out or anything like that. I have been working through feeling hurt (by my own thinking), but could use a little extra help. Here’s what I have as a sample model:

C: Didn’t get an invite to friend’s wedding.
T: I wonder why she didn’t invite me?
F: Hurt
A: Don’t reach out to friend.
R: Retract, don’t connect.

Thanks for your insight.
