Had a friend over for dinner last night, were the same age been friends for about 10 years always got on well. She has a boyfriend she's been with for about 5/6 years now, they live together, have a mortgage etc no DC.
The subject got on to girly talk wine was possibly involved and she said her and her DP hadn't DTD in over a year because she just didn't want to. We talked about that for a while general chit chat then she dropped the bombshell that it's ok it doesn't matter cause she's getting it elsewhere - a guy she works with.
I was 
to say the least. I don't know her DP well but my heart sank for him. She complains about him at times, says he's a knob etc but there's no excuse for it really! I've been cheated on in the past and so has she! I can't understand why she would do it - she's basically actively having an affair with her colleague.
I'm shocked and actually pretty disgusted with her which is sad because we were quite good friends.
AIBU to distance myself from her now after this?
