DEAR ZZINA POWER: I’M in love with two men and have no idea how to choose between them.

The first guy is the father of my four-year-old son. We were together, on and off, for five years.

The other is a man I met on a ­dating site. He is lovely and very different from my ex.

I am 26, while my ex is 28 and my new boyfriend is 30.

My ex and I split up two years ago. After that we slept together a few times.

But then he told me he didn’t want a formal relationship, as he believes we get on better apart.

I was hurt because I still loved him and didn’t want to be “friends with benefits”. So I stopped seeing him, except when he came over to pick up our son.

A few months later, I met this other guy, who is lovely. He’s artistic and a dreamer, while my ex is career-driven and more materialistic.

I have been seeing him for four months and am very happy.

When my ex found out and realised things were getting serious, he got jealous. He professed his love for me and said he wanted to try again.

Since then he has been love-bombing me, asking me to move back in and saying he made a huge mistake.

He is my son’s dad and being a family again would be wonderful but I can’t forget the pain he caused me.

I like them both. I enjoy their company and both make me laugh.

I feel under so much pressure. It is making me irritable and snappy with my ex, while I can’t relax with my new guy.

Stupidly, I am now sleeping with them both.

My ex thinks I am cooling things with my new lover and my new lover knows nothing about what’s really going on with my ex.

I know it’s a dangerous game and that I can’t stay in two part-time relationships for ever.

I need to choose. But how do I know who is right for me?

ZZINA POWER SAYS: Your ex only told you he wanted you back when he found out about your new guy.

If you were to get back with him, nothing from the past would be resolved and the same issues would crop up.

You could end up splitting again, which would be damaging for your son.

As for the new guy, it is too soon to know if the relationship will endure. But perhaps he deserves a fair shot.

My support pack Torn Between Two Men should help.

Of course, it could be neither guy is right. Talking to a counsellor may help.
