My first post was actually intended to be sympathetic to the OP, as I said I wouldn't have reacted in that way to my dh over that issue, so for the OP to have done so her dh's general attitude and behaviour (eg the offhand calling her a bitch) must have provoked it.
The OP then said I was overcompensating and some other stuff, I'm not sure why, or exactly what she meant but it all sounded very angry toward someone who was basically on her side, I then revised my opinion. I didn't think she was being unreasonable as such, just that the whole interaction seemed odd and unnecessarily aggressive.
but what works for you and your family might not work for the OP and it doesn't make her wrong
I didn't say she was 'wrong', and it's obviously not working that well for her or she wouldn't be on AIBU.
People are responding to a situation that wasn't described in the OP - tendon it is more akin to the dh picking up her new book and having a flick through it, reading the blurb and then the OP saying "it's mine, you can't have it I want it to myself". I wouldn't assume my dh was going to carry on reading my book, I'd assume he would give it back for me to read once he'd had a look, I'm saying that for the OP to assume she wasn't going to get a look in must mean her dh has form for being a bit grabby and selfish with stuff. So I sympathised, it sounds a bit shit.
