DEAR DEIDRE I am having best sex ever with gym hunk but I feel so guilty for cheating

DEAR DEIDRE: I’VE been caught in my own trap and it’s torturing me.

When a gorgeous fitness influencer started to show an interest in me, I lied and told him I was going through a break-up.

In truth, my long-term relationship had become stagnant.

Still, I was so flattered and excited that someone so popular, fit and knowledgeable would fancy me.

I wanted to explore how things might develop and spared little thought for my lovely boyfriend of five years.

I’m 28, my partner’s 30 and the fitness influencer is 32.

The connection with him was unlike anything I’d ever felt before and I literally ached for his touch.

Eventually we were leaving the gym at the same time and he asked me if I’d like a drink.

He said he felt stuck in his dead-end relationship and needed to meet the right person to help him get out of it - then looked deep into my eyes. I nearly fell off my bar stool.

We met a couple of days later and went back to his flat for the most intense sex I’ve ever experienced.

That was six months ago and although the sex is still incredible, I feel awful about what I’m doing to my lovely boyfriend.

Added to which I’ve noticed red flags. A few times he has left me alone while he goes off to make a call.

I’ve also found out he’s been secretly watching me. He went ballistic when a guy approached me.

And he asked why I still held my boyfriend’s hand — now I’m thinking he followed us.

He says he won’t leave his girlfriend until I prove I am genuine.

DEIDRE SAYS: You’d be well advised to start running for the hills.

This man is manipulative and controlling, so listen to your instincts and walk.

Do you have any proof that he’s truly miserable in his relationship?

Your boyfriend sounds like a lovely man, who doesn’t deserve this betrayal.

Long-term relationships can easily get stagnant if you start to take each other for granted.

Focus your sights on your relationship, and talk to your boyfriend about how you have been feeling.

I’m sending you my pack Relationship MOT to help.

If after this effort you still feel things are flat, then you need to do the decent thing and think about breaking up.
