You should just set boundaries. Talk about how often you want/can communicate and what you both can do with that availablity/need. If that frequency is not the same between you two just end it.
I recently had a thread asking how often should you talk to someone you’re shukansi with. I thought everyday was too much. However a girl cut it off with me last year cause she said I would contact her too much.

So it depends on the person you’re seeing and how busy you are as a person.
something I learned was girls don’t like guys that reply quick for the most part. They say they do but they be lying.
Edit: I just sent someone a double text after writing this out
