DH has a female colleague that he works closely with. 10 years younger, pretty, etc etc.
She actually works in a different office but because they work on the same projects and their job involves travel around the country, they regularly go away for one or two nights together to work on something. Think once or twice a month.
At the moment, I have no reason to suspect that anything is going on between them. I do suspect that DH may have a little bit of a crush, in that he has talked about her in a way that has set my spidey senses tingling. Nothing implicit, just the way he has talked about her I suppose. She also has a partner. Not sure if married. I've heard them on the phone when DH works from home and they definitely have a friendship beyond a standard professional relationship.
However, in October, the pair of them are due to travel abroad. There are two different things they need to attend in different parts of the same country. As a result, they will be away together for almost two weeks, and have a few days in between the two events. So they will essentially be having a mini break together.
I won't be able to join them for the days in between because it's long haul and would involve taking the kids out of school, plus I'm not sure we can afford the flights (company will pay for DH).
How would you feel about this if you were in my shoes? I'm trying to process my thoughts beyond my initial gut reaction that this could potentially be a disaster for our marriage.
