You sound really insecure. Why do you feel so insecure? It's definitely an issue that you're going to have to deal with or it will most definitely ruin your relationship and any other future relationships you may have.
Maybe he is busy. Maybe his phone battery has no power.
Let me put it to you like this. How would you feel if your parents constantly blew up your phone with messages and calls? Asking where you are, who you're with, what you're doing? Would you feel happy about it? They love you and you love them. You don't constantly blow up their phones 6 times a day. You must love in such a way that the person feels free. Time to look inward and sort this issue out.
I hope you find the happiness you deserve.
