I've been with my wife for over 15 years and we have a young family. I changed jobs in 2015 and a friendship grew with a colleague who works for another company. I have very regular work contact with her (meetings/emails/phone) and she's single.
We recently discussed that we fancy each other and we've had multiple conversations about it since. Nothing at all has happened physically.
The attraction has happened over a period of time - we get on really well, have plenty in common and it's clear there's a connection there. My wife knows somethings up and thinks it's work stress, but the truth is I'm finding it hard to think about anything else. I know it's something that will pass, but I'm struggling concentrating on anything other than thinking about her at the moment.
From the outside looking in I know I shouldn't go anywhere near a relationship with her, but that doesn't stop me wanting it so much. I know I need to concentrate on my family and try and forget about her.
So - my question is - nothings happened apart from us knowing that we like each other and probably some form of emotional affair in that we've discussed things with each other we probably shouldn't. I know we'll stay good friends for a long time. How do I stop the romantic attraction and constant thinking about her?
