I caught husband cheating with work colleague and I am struggling to forgive him

DEAR DEIDRE: MY husband has been having an affair with a woman half my age but insists it’s over and was “just about the sex”.
It feels like so much more.

She is a colleague who has been working closely — too closely — with him on a building project.

I had a gut feeling that he was cheating on me and followed him to a pub car park out of town.

I watched him get out of his car, walk across the car park and into the arms of a much younger woman.

I am 46 and my husband is 48.
