DEAR DEIDRE: WHEN my wife got a promotion and a big pay rise, I thought money worries were behind us.
But it was the beginning of our problems.

I am convinced her boss promoted her to get closer as they are now having an affair.
Months ago I started to feel our relationship shifting.
She had always been so thoughtful and considerate, but she became impatient with me.
Our sex life followed the same pattern and deteriorated from loving and exciting to non-existent.
When her company had a party last summer, everything began to fall into place — it became obvious something was going on between this man and my wife.
He is 44 and was all over her, barely leaving her side. I questioned her on the way home, but she said I was jealous and paranoid.
I am 37 and my wife is 34. We have been married for five years.
Recently she announced she “needed space” and was going away for a couple of days on her own.
She must think I’m stupid because I found pictures of them acting as a couple plastered all over social media.
I realised she wasn’t telling the truth so I did some detective work and started looking at her work colleagues’ social media.
An indiscreet director had plenty of images of them behaving like a couple at a wedding in a Scottish castle.
Scrolling through his feed, I realised that plenty of her “late working nights” were boozy work dos.
I know I shouldn’t have but I contacted her boss’s wife and told her everything — she deserves to know the truth.
She is the mother of their two children and was distraught.
My wife and I have now split up and I moved out a month ago but I’m not coping.
I feel so low and don’t even know what the point is any more.
