I can’t stop having sex with my ex even though he doesn’t want to be with me

DEAR DEIDRE: MY ex has made it clear he doesn’t want to be with me, but I can’t stop having sex with him.

He has a new partner and I know he’s bad news, yet I don’t seem to be able to move on.

I’m 29 and he’s 33. We split up a year ago, but I’m still not remotely over him.

We had a fiery relationship and argued a lot while together.

Arguments were usually resolved by ending up in bed, and the sex was always very intense and exciting.

But we had one row too many...
