I've posted here before but had the thread pulled as I felt it might be too indentifying. Second time lucky...
I saw emails between my DP and possible OW (when I was using his phone for something else).
DP had mentioned going out with work and was it convenient, it wasn't so I said it was better if he didn't go. He seemed fine about it, and I had no concerns.
Then I found emails to OW along the lines of:
DP: I can't come to x event sorry
OW: Oh no!
Dp: if I was there you wouldn't be alone (plus loads more her not having to share with a female colleague if he was there)
OW: I'll wear the suspenders you liked on my FB pic
DP: Dance for me in them
OW: if you make it worth my while...
DP: you'd better not fall in love with me
It went on.
Before posters who've read my previous post pick me up on discrepancies, I'm really sorry I've written this from memory when I saw the emails on Saturday and am trying to repost as accurately as possible.
He's away until tomorrow and I haven't confronted him, I got great advice before and I'm really grateful for any ideas anyone has about how to best deal with this.
I was angry; now I'm just sad.
