I can't even see Realms anymore, and neither can Tara. We've been trying to log in, but all we can see is a huge ad for Realms, asking us to buy them. It's been going on for a while. I'll check again, but I have my doubts that I'll be able to access it.
Is your minecraft client set to 1.8.9? I will also check you are both still invited but I have not removed anyone from the realm so that is unlikely it has happened
