Is this strange?

So I agreed to go out with my coworker, during the first date he said he was also going on dates with another girl. However within a few minutes he said he was moving cities and would really like me to move somewhere close to him! He then spoke about marriage (in a few years) and asked how I'd feel if he came into my life. If he's dating other people, and doesn't yet know how I feel about him, is this convo normal?
