Background:
Me and dp have been together 11 years, 2 dd's.
Have just found a sent message on his phone to a number I dont know saying 'I'm in car park with Gemma'.
I have never heard of a Gemma.
I've tried calling the number on withheld but switched off.
What's the best way to challenge him on this? He's at the gym and left his phone at home. I need to know what to say when he returns in an hour.
Shall I just come out with it and put him on the spot and say 'who's gemma' as soon as he walks in?
Name changed and sorry for typo's - I'm panicking!
