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

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