A few weeks ago DP added an old school pal to his facebook. He'd not seen her for 20 odd years so was understandably shocked to hear she had had cancer and was now in her 2nd remission. Lots of private messaging back and forth. I let it go. Then I found out she'd been in to see him at work a few times (he works in the town she lives in so all legit probably) and then exchange of mobile numbers etc. I commented once that they seemed to be getting quite close and he went mental and said I was heartless to accuse her of that after all she'd been through. I felt awful and so left it.
Anyway I recently stumbled upon some private messages between them where he's slagging off a holiday I had booked and she's agreeing with him that it sounded shit and in future he should go to her and she'd advise him on stuff like that!!!
Then last weekend we were away (funnily enough in the place where she visits her own partner often) and she was there at the time. DP asked her if her and her partner would like to meet up with us and she suggested that he "Lose" me around the shops, she'd "Lose" her partner in the bar and her and DP could "catch up properly" over coffee.
Am I being overly paranoid here?? I don't want to accuse the woman of anything as I know she's had a hard time but if she IS coming onto him, what can I do without sounding heartless??
