My fiancée's family is saying really horrible stuff about me but am not aloud to confront them as my fiancée says they are sensitive?

They constantly question our relationship especially his sister, but should I be able to confront them about the things they have said as some of the things said has really affected my mental health and my self esteem?

I've basically been told by my fiancée that he is stuck in the middle and wants a relationship with his family and doesn't want to pick between us, even though he has told me a lot of the things his family have said about me, needs proper opinions from both guys and gals here!
