Ok I will try and keep this short and factual
Picked up DH's phone and was flicking through texts - discovered a whole load of texts from him to a woman - D -.
Confronted him only to discover that the woman is in fact a close friend of mine who moved abroad about 10 years ago - he claims this has never gone anywhere started as a bit of harmless flirtation and has happened intermittantly over the last 10 years. the time I found was back in November when I was away for a week - texts are quite explicit. He says it stopped because he 'oversteppped the mark' and she did not reply.
He is trying to convince me its just a bit of harmeless fun between them that was never going anywhere.
She won't speak to me - have called her to ask what is going on.
What do you think?
