I posted a response about this on another thread about affairs. But I think I need some advice of my own:
I have just found out that my partner of 5 years fell in love iwth a woman on a work trip abroad about one and half years ago. It was a very intense frienship to start off with but developed into a massive infatuation. They kept in contact via email (I recently found the messages) and he declared his love and admiration for her many times. It came to and end a few months later, I'm not sure how - he woke up, she was more sensible. Our relationship had always been really good on the whole and I never guessed at the time, though I was jealous of their friendship.
However on discovering these messages I have found that he is trying to rekindle the friendship or something more I'm not sure (he sent her a song called 'Nothing without you' - am I a fool to believe this was an innocent gesture?) He is due to meet her again (as part of a group) through work and says he wants to get rid of the tension.
He seems devasted about the whole thing but I just don't know what to believe any more or what to do. I'd be really grateful for some advice.
