My sisters partner is at my house this week with her. I am trying to like him, be nice but I just feel so tense. So much that I'm finding excuses to be out and even stay over at a friends house! He tries to make jokes towards me, calls me kiddo and stuff (we are the same age) so I think he is oblivious to the tension that I feel. I just do not trust him or feel comfortable around him! I feel he controls my sister, is disrespectful i.e. Smokes weed in my back yard like it's normal and is loud and embarrassing. When she asked to visit I hoped she would come alone, although I knew this wouldn't be the case, and now I'm feeling tense in my own home! Any advice on being able to just chill out and be able to feel neutral towards him?
