Co workers are nosy about dating life?

Some co workers who I barely know love to gossip and get into everyone's business. It's starting to make me uncomfortable. They've been asking me if I'm dating anybody. I explained that I'm still getting over a past relationship that was long term. You'd think they'd respect it and not pry. But they felt it was appropriate to ask if me and my ex still hook up. If we still hang and why. They asked why we aren't still together if I liked him so much. These questions are upsetting because I'm very broken hearted and vulnerable. I also don't feel comfortable sharing private information that should only be between my ex and I. How do I get them to back off without sounding mean?
