I feel a bit of confusion around missing someone.

I recently started dating someone. We connected very quickly and it seems that we are both really interested in each other. We both have busy jobs so its usually at least 1 week until we can see each other.

I just want to understand the emotion that I’m feeling and understand if it is healthy or not. I feel like a ‘pull’ when I think about him (I guess this is ‘missing’) and perhaps a bit of frustration and anticipation too. I don’t think I’m in a rush, but I do feel like I really want to see him and I miss him.
It doesn’t feel bad as such but it feels unsettling, because it’s unfamiliar, it feels strange. It is still very early days in the relationship.
