I caught partner having sex with his ex-wife in my home – my trust is broken

DEAR DEIDRE: MY partner cheated on me with his former wife and it still haunts me.

I caught them in the act on our sofa after returning home from work early.

Although it was years ago, and it’s now 12 months since we split up, I still can’t get the image of them having sex out of my mind.

I feel like my trust in men has been broken for ever.

My ex and I are both 50. We met when we were in secondary school and clicked, but our friendship fizzled out.

Eight years ago...
