I am sorry you are sick... and hope you feel better soon. Tempest definitely does not like her space invaded that way and this is very, very common. I have a girl like that and a boy who still likes to tease her but they live quite harmoniously together. The girls can be very loud too and make it seem like it is much worse than it really is in "cat talk". Separating them is fine OR having somewhere she can retreat to where Sinbad can't really get to her is a plus. This process can be very long and arduous on the guardian so take a deep breath. This is all part of them figuring out their boundaries with each other and Tempest trying to let Sinbad know when he has gone to far. I never separated my girl and my naughty boy but made it clear to Wendall that I was not happy with him chasing Perla OR cornering her. He never makes contact but closes in on her to tease her. My Wendall is just a brat and I think Sinbad is not, he is just really wanting to play. In time, Tempest will realize that he is not a threat but more of a nuisance and begin to calm down a bit over his advances. :cross: I am hoping for the BEST for your two kitties.
