Talking stage

Hi everyone I’m getting back into the dating scene and I’m just curious but do I have to talk to the person im interested in every day??? Sometimes we may talk all day but not the next couple of days how do I effectively keep up communication to show im still interested? Sometimes I really don’t have anything to talk about and don’t wanna waste a good amount of time talking about something random that I really didn’t care to talk about. Should I aim for At least once to twice a week or whenever we can?? I get nervous talking to people but also nervous if I don’t speak for long especially while dating…
