To set the scene a little I've been with OH for almost 3 yrs since DSD was 10. I was not the reason for her parents' split they'd been separated for a year when i met him. I've tried and tried and tried everything to have a good relationship with her but it just hasn't happened despite having a very good relationship with her brother aged 17. We have a polite relationship but are not close and she does her best to stay away from me when they visit 2 or 3 times a week and EOW.
Anyway to get to the reason for my post. I've just been having a clean up and although I rarely go in her room I thought it could benefit from a dust and Hoover. On top of her bedside cabinet I've found an old tissue box crammed with used sanitary towels. There is a bin in both of our bathrooms which are emptied regularly and if she was too embarrassed to put them in there, there is the outside bin.
Her dad would not be comfortable having a conversation with her about this. You may flame us for this but it's simply not an option, he'd just refuse.
Would AIBU to contact her mother (who I've never spoken to) to ask her to show her how to hygienically dispose of her sanitary pads?
