Long story short, become single a few years ago (horrible, complicated breakup from abusive ex), finally got a bit of confidence after some time and had FWB situation. Very casual, also made very clear it wasn't going to lead anywhere. Lasted on and off for maybe 6 months or so, speak now if we see each other out although don't see each other often at all nowadays.
Forward to now, a year later, FWB's friend whom I've never met is out with ex-FWB and other people, randomly including DP, the FWBs friend pipes up "I can't keep up with who is sg who in this town" I.e. me and insinuating this FWB situation is very recent and overlapped with DP, which it most certainly hasn't. Who even says stuff like this out and in a group of people. I actually trusted FWB this was just something we kept quiet and so long ago didn't think it would ever be mentioned (why would it). DP is now questioning my loyalty and I'm so annoyed the past is being dragged up like this. For men always seems it's fine to have all these one night stands or women on the go yet women aren't meant to do anything like this. Maybe I'm BU but needed to rant!
