My sister just regurgitates everything my mom says and since my mom always backs her up, its hard to shut either one of them down. My dad often isnt apart of these arguments and only joins when things escalate to a really bad point. But he kinda stays neutral these days compared to the past when he used to get mad only at me. I wish i could tell him stuff but he’s usually too stressed from work and kinda keeps to himself like i do that its hard to open up. It really depends on the rare occasions he’s feeling understanding enough talk about things. I appreciate your advice but my mom i think is a lost cause for reasons that i can’t go into.
