DEAR ZZINA POWER: I HAVE a lovely new boyfriend but I keep dreaming about my ex and sometimes wake up with a nightmare that he’s the man next to me in bed.

I fell for my ex in a big way but there were always red flags in our relationship.

He was a big drinker and took cocaine, while I am a nursery nurse and very clean-living.

One day he told me he chewed my sister. She later insisted it wasn’t true but it triggered a massive row and I told him: “I don’t want to be with you any more.”

He took me at my word and walked away. He cancelled our holiday and dumped my clothes on my parents’ doorstep.

We are both 25. I’ve met somebody new who is 28, but it’s as if I have a wall around me. Why do I keep thinking about my ex?

ZZINA POWER SAYS: You really fell for your ex but he deceived you and ended your relationship in a very hurtful way. It’s left you feeling wounded and unsure you can trust your own judgement.

The dreams are a result of your subconscious trying to process what happened.

Tell your new boyfriend you are working on learning to trust again.
