I have worked with this girl about six months. We have flirted non-stop since the day we met. Recently she?

broke up with her boyfriend. She said it was because she liked me so much. I was hesitant because we work together. Eventually we started making out from time to time and I gave her manual stimulation with my hand. However, I have tried to maintain my distance because we are colleagues. All the sudden she is telling me she is trying to get back together with her ex! A week ago she said he was pretty sure she'd follow me a long way and giving me eskimo kisses and romantic crap like that!!! I am so unbelieveably jealous and sad. She says its because it doesn't have to be a secret with him. Is she trying to break my heart!?!?
