How do I act around him now?

we never argued, and were always loving. he broke things off telling me he's not ready, that he doesn't truly mean it when he said he loved me, that he hasn't given thought to his feelings. He told me he doesn't want to give me half baked feelings. I still deeply love and care about him, I don't know how to act around him (we're colleagues who work in the same department so I can't avoid him). I am also someone who finds it difficult to mask my emotions and fear I will burst into tears when i see him again. After the breakup he and I haven't spoken, what do i do?
