I have been in a similar place with a partner too. It is a terrifying state I have never seen in anyone else before… pure catatonic episodes. But there was a level of extreme paranoia and at times I would be accused of conspiring with an ex (who I didn’t know) to ‘get’ her. This particular relationship that I had was extremely tough and left lasting damage on me - enough for me to avoid any intimate relationship for a few years till i could recover. I hope she is doing better now.
