I can’t stand my sister in law. My partner found his brother 3 days after he died. my s.i.l reckons she felt something had happened the first night but yet didn’t phone police to do a welfare check or check him herself. Instead waited 3 days for my partner to come home from a veteran weekend where he went to help with his ptsd. What pisses me off most is she doubles down knowing that he has ptsd saying he was the right person to find him and she always wants to play victim. Nothing is ever her fault. She emotionally manipulates people and I see her for who she is. I’m trying to keep my cool and I’m struggling. There’s soo many things I want to say and I don’t because I will go below the belt. It’s frustrating the way she treats my partner and now he doesn’t want nothing to do with her yet she still puts him down through texts on phone. I can’t say nawt as I respect my partner but I honestly don’t know how much more I can keep my mouth shut until I say some home truths
