I am ... not getting the hurt over someone LW has presumably not spoken to in probably over 10 years not inviting her to their wedding. At all.

My fiancee and I are intermittently planning our wedding, and I'm holding firm on "no one who hasn't reached out to contact one of us in the last year is guaranteed an invitation". It has seriously cuts down on the guest list, especially in the category of "friends of parents and distant relatives".
