I borrow my DPs phone to check my mail as I'd ordered something I was excited about, and DP hands over phone without even asking what I want to borrow it for, which is pretty normal for us.
I open the browser app and see what appears to be a facebook account. I am struck by a peculiarity of the visible friends list, and realise it's a different fb account in DPs name... mostly I just feel guilty for being there and prying, so I close the page and get on with what i was doing.
Trouble is I've now opened the box, so to speak. Why does DP have a separate account that appears to be secret, while maintaining another I know about? Why does it have not work contacts or anything, but people of the opposite sex we have never had more than a passing acquaintance with as friends? Do I ask, or do I shut up and trust and take this concern as the rightful price I pay for (albeit inadvertently) prying?
I don't think impropriety is generally very likely from DP, so I don't know.
