Host never expresses emotions, lets people walk all over us

I keep getting hurt by the same people over and over again. I am angry at them. I can even be furious!!! But the host (which almost exclusively deals with socializing and dealing with other people) won’t do or say a thing about it. And then we get hurt again. And again. And again. Same people. Same hurt.

The same liars lie again. The same betrayers betray again. Yet the host is surprised and shocked every single time?????The other parts suffer immensely while it happens (self harming, controlling and paranoia parts return, happier parts disappear) and the host still doesn’t suspect a thing until absolute proof appears….. How to get out of this cycle? It has gone beyond the point of naivety and is more like denial at this point.
