AIBU to feel I'm not in the wrong.DP& I together as family 7 years. My DS 11 & her adopted DD 15 (adopted 8mon before we got together) so a tough family dynamic. I find her DD very difficult so don't have a really warm relationship there however DP finds her DD & my DS very challenging. I am pretty strict but tend to ignore rather than cause unnecessary confrontation. She won't let anything go & DC get barked at morning, noon & night. They can't say they're sick or tired or hungry. It's boot camp in the extreme & they don't get an inch to breathe before they're being shouted at for something or nothing. DP is critical of them every waking hour (some of DS habits 11yr boy are gross) but zero tolerance & screaming doesn't help. DP tries to catch them out & if they try to reply truthfully they get roared at for giving cheek/answering back. When I try to stick up for them, or don't join in her rant I then bear the brunt of it for undermining her, not respecting her etc. AIBU to think the kids need a bit more tolerance?
