Aquarius guy (my friend) and his tests/games

Yesterday, he calls me. I did not hear the phone. So I txt him back and I explained to him tha I will call him after I unwind and that I just got home. I called. No answer. I txt him again. No response until 3 in the morning from him saying, I'm sure you are sleep so let's talk tomorrow. Mind you prior to that. I woke up 5 min. Before he txt me this message with him on my mind out. I was pissed that he did not call or txt, so then a txtcame through from him telling me this. So I txthim back, like yea we will talk later and that he was on my mind. But Iwas cursing at him. So he txt back to say its a good thing that I'm on your mind. And that he actually love to hear me curse. (because this whole time, I never cussed at him like ever). Because he is so darn sweet! So I told him that I was not mad but he needs to do something about when I call, he needs to answer. We don't see each other. He can take a plane ride here if he wanted to but I understand that he really is taking things slow with me. I find that attractive really and I appreciate that about him. I mean some guys would be all over me ready to see me, etc. but he is really taking his time with me. Out of the three months, we are still learning each other of course. He will tell me he wants to see me after I tell him. It I do not say it often after he kind of pulled a way with the phone calls after I was telling him I miss him like way too much. So I stopped the emotional bs. I just don't like the fact that he won't let me know his many "layers". It's like he does not trust me yet. And that is what I hate! I want to open up to him so bad about alot about me but I am afraid to do so because of the whole thing of aqua men don't like open books. I mean can y'all tell me how can I be best friends with him without telling him everything? Give me some examples of how to handle this? I want to talk to him about my past, my present and things concerning my future but how do I still be a mystery to him?

My question to the aquas, men and women too, what can y'all tell me about this "relationship" b/w me and him so far? Could it survive? Is it on the right track? Do you think he likes me alot? Everything I read so far says Yea he likes me. But can you guys give me some more ideas or tricks to keep him interetested?

Thanks to all in advance!!
