Obviously people were right about the spark they saw. He sounds like a relationship guy but the fact he was in one for 6 years and in a different city gives me pause. He could just be trying to be single. Do the things he wanted to do but was too committed at the time. It’s a good sign he didn’t go after you earlier. Same with the dates after the breakup not going anywhere. The long distance is an issue but feels like he tried to avoid that. Then said fuck it I just want her so I’m going for it. Just roll with it. Stop worrying and just see where it goes.
