BFF. Been with her DH for 25 years +, we know them both well, seemed really solid but he has suddenly announced he wants to separate with no real reason given. They have 3 DC, youngest is 8. She’s been completely caught unaware by DHs sudden request to call it a day.
Does he have someone else in the picture?? The cynic in me says yes because I don’t know a single couple where the man didn’t have someone else when he was the one to end the relationship. Either having an affair outright or someone waiting in the wings.
YANBU - he’s got someone else in mind/ having an affair
YABU - you’re a cynic! Sometimes it’s just as it seems and he’s got other reasons.
