We’re not married so not technically a stepparent. My daughter is 14 and going though an incredibly difficult phase - she’s been suspended from school twice, been caught drinking on one occasion, I suspect she smokes. Dp finds her behaviour almost unbearable and doesn’t like to be around her. She is rude and disrespectful, not particularly to him personally but he takes her behaviour personally. He says she has a dad and it’s not his place to get involved and they are basically strangers. He has a daughter aged 11 who is very well behaved so he can’t relate from personal experience. I’m incredibly stressed from dealing with my daughter and I feel like I’m not getting any support, I discipline her but I am really focussing on managing her behaviour rather than being angry and reacting to it. Everything I’ve read suggests things would be better if he was involved but it won’t happen. Am I expecting too much? Is it reasonable from him to remain detached?
