How often is normal to see your S.O. if you live in the same city?

How often is “normal” to see your boyfriend/girlfriend (when you live in the same city)?
I know there is no such thing as “normal” and every couple is different, but rough estimate? I currently see my boyfriend about 1–2 times a week and I feel it’s not often enough, but I’m not sure if I’m expecting too much? (takes about 30 minutes by bus from my place to his and vice versa)
