Search Results: he always tries to keep distance

We broke up a year ago. We dated for 5 months. I wanted it to be official but he wasn't ready for a relationship because he had to find himself. He was moving also away and it was doing to be hard to do long distance. I wanted it to work but he didn't. I got stubborn but also knew we needed to stop contact so i told him i had to block him then took him off my socials. 7 months passes he returns to my city. He bumps into my mom and asks about me and if im single. My mum told him to chat to me. We then planned a day, with no small chat. i waited that day, then he never showed. I got frustrated and thought thats it. I then bumped into him 2 months after and he was super shy. I approached him in a warm manner because i do still care about him but had moved on emotionally. I then asked why he didn't show up that day and he said it was because of nerves. I then left and emailed him that night and told him i do still care about him and i always will but i have to do whats best for us, then wished him well and that ill see him around. I bumped into him yesterday, and insisted on stopping me when i told him i was busy, so i did. he was so friendly to me, flirty, and kept trying to make me smile and laugh where i really wasn't giving anything but smiling and laughing and wasn't so chatty.

What is he thinking? Is he trying to woo me again?

Let me start this off by saying this guy is one of my coworkers/supervisors.

We met at work and I noticed that he would come and talk to me pretty dang often. It was initially awkward at first. I'd be folding clothes and he'd just come up and ask me how I was doing. When I said I was doing fine and asked him, he would reply he's okay or something then just stay beside me and help me out.

As we talked more, it became less awkward. We shared lunches. We exchanged stories. We would try to schedule our shifts the same just because work was more fun that way (and no, we weren't any less productive. Our managers actually pulled him aside to let him know relationships with associates were okay as long it didn't interfere with work. They said to keep up what we were doing or else they'd intervene - even though we weren't in a relationship.) He laughed at them when he was pulled away for that.

Anywho, this guy has volunteered and actually gone on business trips with me. I'm applying to grad schools across the country. He knows I'm scared of planes and travelling alone so he just volunteered to come along. He drove me everywhere. Helped me with everything at the airport. Comforted me through a panic attack on the plane. I didn't even have to pay for his ticket/hotel (even though I tried to).

After my interviews, he would be there with coffee (in the cold states like Michigan) and would always be ready to take me to dinner or a nice drive to get my mind off the interview. At one of the interviews I did a lot of walking in heels and ended up with 3 blisters... which he bandaged for me while I was sleeping (I had ko'd after going to the bar because I had a rough interview).

No guy is just this nice... right?
I've tried to distance myself a little bit, but he's told me that he doesn't mind caring for me because I'm important to him.
