About 20 years ago I used to work with this bloke and there was always a bit of a spark between us. Five years ago, very bizarrely, in another country, we ended up working in the same office again. The spark was still there and we often went out for a drink and/or dinner in the evening. DH knew about it and didn't say anything, even when I rolled in pissed once at 1.00 am. Blokey moved to another country two years ago. We e-mail every day - about 20 e-mails and meet for lunch about every 3 months in Paris when he is passing through Europe (now in Far East - him, not me).
Although there is definitely a spark there, there has never been any physical contact between us - not even a social kiss. But a friend showed me an article in, I think, Eve magazine, which said that this sort of thing was infidelity and "unsafe" if you are happily married (which I do consider myself to be - he is still resolutely single, though does have an on/off girlfriend).
So, Mumsnet Jury, is this "relationship" infidelity, wrong or OK?
