I’m so sorry for the pain you’re feeling.
I know what it’s like to feel invisible. It happened to me on several occasions, and it really hurt me.
On one occasion, I was invited to a friend’s surprise bridal shower (we had been pretty close in the past, and lost touch). I happily came to the shower where EVERYONE was talking about the invitation and the upcoming wedding (I never received an invite). I was MORTIFIED and said nothing. When the kallah walked in, she saw me, and tried to fix it by awkwardly asking what my zip was, and, oh, she must have written the wrong zip (her reaction was a dead giveaway to all). Real busha.
I know it’s not the same thing. I think inviting everyone but one is rude.
