When my now SIL met my partner, she was very expressive about how attractive she found him. Constantly told him how hot he was, called him endearing names and was overly flirtatious. It was hard for my partner and I because although we felt uncomfortable it was a weird dynamic given she was with my brother and we didn't know how to shut it down. We've learned as a couple to never allow someone to be inappropriate for our attention again.
Anyways, fast forward two years later and it stopped BUT I still have this real hatred and distaste for her and of course it's really affected my relationship with my brother whom I used to be very close to. I don't trust her at all and don't feel comfortable with her around my partner. She makes me feel unsafe. How do I get over it so that I can actually have my brother in my life?
