Have name changed for this post.
Went to a party at the weekend a client of DH. A number of his colleagues were there. I don't know any of them very well but one girl was clearly talking about me and looked away quickly whenever I looked over.
I checked his phone last night. DH works very closely with a very glamorous and beautiful former model. In amongst lots of very normal professional emails there were various email exchanges between them which were not professional. They contain lots of smilies and winks (which is very unDH).
By way of example.
Girl - I feel really tipsy after that drink
DH- have some more
Girl - I really do feel tipsy. someone might take advantage
DH - Come and have another bottle. In here.
Girl - are you hungry yet. I want to go
DH - bit busy don't wait for me
Girl - of course I'm going to wait for you.
DH - Tea
Girl - no thanks
DH - Oh. That was a short conversation
Girl - got any gossip
DH - only that you came in looking very ruffled earlier covered in make up and dodgy stains.
Girl - I must be having an affair.
I am mad. Am I overreacting? To me this is crossing the line and goes beyond normal flirty behaviour.
