Will be blunt. When I met DP he hadn't long separated from his wife. One of her friends was trying to shag him (and he said he would have done it if he hadn't met me - his wife cheated on him so think he saw it as payback) as was a woman he worked with at the time whom he also said he would have slept with had he not met me.
A year after we got together he was hospitalised and I accidentally (really wasn't prying - would admit if I was) saw a Facebook message to the nurse that had looked after him in hospital. Think he knew her before the hospital stay as they had a couple of mutual friends. He'd messaged her asking how she was and saying 'it wasn't the same without her looking after him.' Flirting in my opinion? Maybe I'm being harsh. But think she felt it was flirty as she swiftly mentioned her boyfriend and sent a message that didn't warrant a reply whereas DPs was quite long.
He still has the two potential shag women as friends on Facebook and have noticed via computer history he's been looking at their pictures. Last week he worked at a different place to usual and told me of a 'funny conversation' he'd had with a woman there. I saw today that they're now Facebook friends and he's been looking at her pictures.
Having them on there makes me think like he's keeping them in the background in case he and I split in which case he'd definitely go there. ExH did precisely that so I may well be being extremely over sensitive. AIBU to be pissed off?
