Last Christmas at a there was a female colleague openly flirting with my partner right in front of me. She made an effort to sit next to him and at every opportunity at the bowling alley tried to make out they were going for the same ball to touch his hands and stare at him, you can tell when someone is flirty and keen on someone. When we left she made a point of saying you won't see me until then as I am on leave and hugged for a little too long. . I said how I found it disconcerting her openly flirting and it made me feel uncomfortable he said oh she says I'm good for an old 'un (she's 18 years younger) and she is very intelligent (which I know he finds attractive) and I respect her. since then when working from home he doesn't always pick up her calls or doesn't always put her on loudspeaker but if he does makes a point of saying I am there
He played one of her answerphone messages and she said I am waiting like a puppy dog for you to call me back, I said what's that about he said I have no idea and appeared slightly miffed.
Anyway she is leaving and she invited him for a goodbye cuppa in the office, he said he'd take me along too which is great but I feel awkward and wonder how to play this if she is clearly going to be the same and will want to hug him etc...WWYD?
They have promised to keep in touch and he will send her his new phone number if he changes phones...
