Red flag or just abnormal?

I (28f) agreed to date this guy (24m) and since we were colleagues we were kinda friends before the date itself. Within a few minutes of the first date, he started talking of marriage (not marriage immediately, in the long run) and said he was tryna look for someone serious. But he later told me he was moving to a different city in a few months and said he'd really like it if I moved to that city too. I said I didn't know if I liked him that much yet. He also asked for me to call him to a family dinner so that he could meet my family.

What's confusing is that he wouldn't touch me at all, he maintains distance and the most he ever does is glance over at me and smile.
