Ah, apologies. You can see why "full apology and promise to stop acting like a cunt" made me think of your ex though.
I'd go back to her and state your case for not having it at your flat - don't let her think she has the upper hand, however well you clean and tidy she's bound to find some tenuous reason as to why it's not child-friendly.
