<human>: This is my first time posting so I'm sorry if I'm not clear or don't add enough information.

I work for a company that employs a lot of people to work out in the field as engineers as well as administrators to work in the main office. I work in the main office, and my coworker was out in the field for the past year that I have been working here. His job recently ended and he moved back to the main office for a short period of time. 

We've had minimal interaction except for maybe a hi once here and there. Otherwise, no contact at all. On his second day back in the office, he emails me a work related questions to which I reply back with a normal response. He then proceeds to ask me questions to continue the conversation. The emails were a little bit flirtatious, but he's attractive so I went with it. He said he didn't know many people in the office and suggested we get lunch sometime. I thought it was a little interesting, mostly because of our lack of previous interaction,  but I agreed. 

Fast forward to lunch...it was pleasant and it felt a little date like. Mostly because we're discussing the normal date topics. He then casually mentions a story regarding his girlfriend. I immediately realize I misinterpreted the situation and switched to friend mode. After lunch, we said good bye and parted ways. Not even five minutes later, he texts me saying he had fun and that we should hang out again soon. He found my number through a company email. He's been texting me since then and continuing the conversation even offering to come down near my place to hang out over the weekend and take me on a motorcycle ride. I'm confused by his intentions! Not sure what he wants and if I'm reading too much into his actions.

And just to be clear, I haven't encouraged any contact etc since I found out he has a girlfriend. I've been cheated on so I am in no way interested in doing that if that's what he was looking for.

Can you condense the text into a few key points?
<bot>: Coworker in a relationship has been texting and emailing me to eat lunch and possibly hang out. Not sure what his end game is.
