If you cant communicate now you wont be able to after a little break, one is more mature then the other and yea its cool to stay friends but who is in limbo land now waiting for him to come/call because he has his space.
The longer your apart the easier it is to move forward.
In your position i wouldnt like to be, to be someone's lapdog and return to his beckoning call wont get you anywhere in life.Playing this game is utter nonsense.If your meant to be and communication is your only problems you should be able to work this out together or after a week or 2 at most.
This is all the time and space you need because if that person is the right one for you he should be going nuts at missing you already.
You sound rather young 18 (at most) and you have a lot of life in front of you, maybe he isnt the right one ?
A mistake is always forgivable, rarely excusable and always unacceptable.
