My 8-year-old is challenging every thing I say and DOUBLE challenging everything Ryan says. It’s causing issues between us. If there’s something I don’t agree with, I say something but I support everything he says. I’m just ready to cry because shit just hit the fan. Hardcore. We rarely fight/ argue but when it happens, damn. Stuff he says to me hurts. Bad. I am trying really hard not to stay calm because of the baby, but it’s really freaking hard. I know Emma is angry about her dad and how he disappeared, choosing drugs over the girls, and Ryan has reassured them in any/every way possible that he isn’t going anywhere but she is just pissed. Yes she already doing counseling and anger management, before any suggestions are made, but she is SO HATEFUL. Then it’s taken out on me both both of them. I don’t know what the fuck to do anymore.
