I am sorry. It doesn’t feel good.

For the sake of understanding situation better and maybe seeking a solution I have a question: is this the same crowd you didn’t want to attend bridal shower with? Because they are much younger, you don’t know them well, you don’t really like them that much? Did you end up going? If not, it could be they thought you don’t want to be part of girl group? If you are invited and don’t want to go up to the point of getting upset over it, then why being not invited upsets you too? Could it be that they don’t invite you because they sense you don’t particularly want closeness of friendships with them?

Have you made any steps to connect with them? Demonstrate wanting their company? Do you want to hang out with them? Or deep inside you don’t, but still feel hurt being slighted (we all have confusing feeling at times)

You don’t have to answer, maybe just food for thought.
