I'm really upset with my husband because he doesn't believe me when I say his sister is toxic. He even asked me if I think I have postnatal anxiety - we had a baby 6 months ago.
I have recently stood up to my sil about her behaviour - manipulative, rude, toxic. She smirks at me and gives me dirty looks whilst no one can see. At family gatherings she gives mil looks if I say something she disagrees with etc Comments and snide remarks etc. Hates when I have conversation with mil, always listening in when we talk, doesn't want me to have relationship with mil. Controlling, thinks she knows everything best. Downright unpleasant to be around.
Once I called her behaviour out she said that it's untrue and started gaslighting and said she couldn't be happier that her brother is with me. I'm sure her and mil talk behind my back.
I am so tired of thinking about this... But I won't give in.
This has affected our marriage a lot. We will speak to a therapist but I just don't know what to do and I am so upset he doesn't believe me.
