How often do you talk to your ldr partners?

23F; 25M

My partner runs a business and he is super busy with work. We talk daily but sometimes it is just 2-3 exchanged texts in the day. We do manage to talk over vc every 2-3 days. Is it fine in a ldr? I do feel the void at times but I feel with that busy schedule this is enough. Just need some validation maybe if it makes sense
