Just to vent

I liked him from the first minute he sit ivy office and told me all those mistakes I made on the reoport was nothing, that was the 3rd or 4th day he became my boss. It was a genuine like though. I cannot figure out since when our conversation turned casual, more friend like than colleague. He teases me offen like "I was the little sister he never had". We flirt often, but with certain amount of control. We both have family and kids, we are not trying. I think I felt myself change, care him more than I should. I tried to leave, found a job, but eventually stayed . He said he "hate his own voice when he has to told someone that I am leaving"... I think I over analyzed his word... I lost cuz I start to care more than I should. What should I do? I can't wait our business trip together, but I wonder how will I react... I don't think I misunderstood him while we were in the car, when he claimed I distracted his attention. He respond to every my text, almost, when I fussed about he not answering my phone he called back right way. Do you like me? I am confused. Do I want to find out? I am not sure.
