I’M being messed around by a girl at work. She treats me so badly, but I can’t stop going back to her.

One day she’s flirty and fun, the next she totally ignores me. She treats me like dirt.

I take her out for meals, I drive her home from work and give her money and then she gets off with someone else right in front of me.

She likes to call me her “friend with benefits” because we sleep together – if she doesn’t have anything better to do.

Other colleagues tell me I’m crazy for indulging her. They say she’s self-obsessed and deliberately cruel.

But I fancy her more than anyone in the world.

When I tell her that she hurts me, she just laughs. She thinks that being a minx is a badge of honour.

I’ve just heard she’s going away for a dirty weekend with a much older, richer guy and I’m devastated.

JANE SAYS: What would you do if she asked you to lie down in front of a steamroller?

You have to wake up and start seeing her for the cruel operator she is.

She might have a pretty face, but she obviously has a very hard heart.

From taking advantage of your generosity to using you for sex, she’s utterly shameless.

Stop allowing her to make a fool of you.

Others can see that she is piece of work, why can’t you?

Surely this weekend away with another man has to be the final straw?

Unless you let her go, she’ll hold you back and mess you around until you’re on your knees.
