Ex Wife Ignored Me?

I was totally ignored by my partners ex wife. They have been divorced for over 25 years and are just barely on speaking terms. We were at a cafe and she said a quick hello to my partner and totally disregarded me and then went on her merry way. Is this normal?

She’s been married twice and divorced and both divorces were very messy. She took both ex husbands to court and took their homes.
