We've talked about deal breakers before, elsewhere; I thought the summary was that while people keep talking, and may initially know deal breakers, more may become apparent.
You won't always know what a deal breaker is until it happens, so it's a bit facile to say that you can set them out.
Wouldn't occur to me that animal cruelty was a deal breaker, because it would never occur to me that DW was a dogbeater... if she became one, it would be.
larrygrylls talked about demanding his DW wore burqua; he could demand that. I assume in this society she'd tell him to take a hike, and it could be a deal breaker for him... that's his problem, not mine, nor his wife's. She could say to him "Wow, sleazebag, visiting lap-dancing bars is a deal breaker.." if he does, and she decides it's over, that's her decision, not mine or his...
DW wouldn't tell me going to a lap-dancing bar would be a deal breaker. Why? Because she knows I wouldn't.
OP has to decide what she wants to do.
he has been on stag dos before and he knows I hate it. I'm gutted, he says I should forget this one "mistake" as he (allegedly) didn't has a private dance as he knows I would hate that. He claims he was just curious (inspite having been before and knowing all about it!!) Being in front of a naked woman that isnt me, for kicks just feels like cheating on some level.
Sounds like she's made views pretty damn clear - and he doesn't respect them, or he doubts her willingness to sanction...
