I think my fiancé is into his sister.
Okay. I'll keep this short and sweet-
My fiancé/baby daddy found out that he was sexually abused by his dad. He would make he and his sister have s** while he watched, when they were little.
My fiancé and his sister are SUPER uncomfortably close. I'm his first girlfriend ever, and before we got together, he and his sister would go out to things like dinners, movies, etc. pretty much like their dating. He laughs and looks at her in a way that he never does with me. Whenever she walks away, he'll look back. It just feels like they have sexual chemistry. She never liked me from the beginning, and always calls me out or tries to make me jealous. There was even a time We were playing a game and I called "uno" out on her and she got mad and left the house.
I've tried confronting him about how I feel about their relationship . Many times. But he gets mad and says "I have a sick mind" should I be worried? I feel like they would have s** again if they could.
