N/c obviously
Husband cheated last year with a business associate (not someone he works with but someone he sees a lot through work). After a separation and mediation, we got back together in the summer. He seemed sorry.
All seemed ok, a bit fraught at times. This week he has gone on a work jolly with a client at the last minute notice - gone til Monday. It is abroad. I don't know why, but I've suddenly become suspicious - he has only been on trips like this a handful of times. I dialled OW mobile number (easy to find online) and it is a foreign dial tone, same as his. She travels abroad now and again, so this isn't really substantial proof but possibly too much of a coincidence.
I think I know the answer, but I need help confirming it. Any idea what I could do? Rubbish at detective work and obviously if I ask, he will deny
