Yoyo - My 2cents is that I think he's looking for you to ask to come. He's afraid of rejection so he's hinting around. However, I think you're playing it right because since he's not convinced enough to commit to it, if you ask to join him, he'll run again. See how the next 2 weeks of his business trip goes, and how much closer he comes to making a real commitment to you. Don't take one step towards him, but make sure he's not fearful of being harshly rejected. It's a balancing act, Sister Goddess!
