How often should I text my guy friend, and how many times during a week should I text him?

I have a guy friend that I talk to I will talk to him 3 times a week. I do not want to scare him away. I only text him because I do not want no one to know our business. I will go over to his house one day a week and see him and talk to him face to face. I just do not want to bother him to much. I like him and I do not want to make him upset. I will not text him and he will text me first if I don't text him.

So if I text him once a day and he replies it is okay. I can go over to his house because he said I can and he wants me to do that.
