This may sound like a silly question but I need more insight before I make any rash decisions: what if your partner was having the EA at work?
Example - he spends all his lunchtimes/breaks with ow- going out for lunches together, having in-depth convos, they have each other's numbers but prefer not to text whilst st home probably in fear they'll be called Upon it (other woman is married)
Also, they go away on work trips together so they will have more time to socialise etc
Would you class this as an emotional affair?
