Does this sound avoidant?

I met someone at an event a few months ago. We went on dates and had a nice time. It's come to a point for me where I see that it's not going to work, and I suspect that he's avoidant. If someone moves around a lot, could that be a sign of insecure attachment? He has lived in 4-5 different cities in the past few years. He moves about once a year, sometimes more. These moves have not been work-related. He makes it sounds like he just likes experiencing living in different places. Some of the moves have been international. He just turned 40. He has been cagey about his relationship history and it's been hard to get clear answers about his past relationships. The last "serious" one was with a woman in a different country and he they broke up when he moved away. Or maybe they broke up before he moved -- I haven't gotten the whole story.

When we first met he didn't mention the possibility that he might move again (his family lives here) but now it sounds like he's been planning to leave this city all along. I feel like he duped me about that. I don't think we're compatible so even if he stayed I wouldn't want to pursue a relationship but I'm wondering if this sounds avoidant. I know it's not enough information to diagnose him but I'm super confused by his behavior.
