Confused Aquarius Seeking Help With Scorpio

Pretty acurate topic if you ask me. Aquarius and Scorpio? I know, it is not exactly the cherry on top however I strongly believe that it can work out. First of all, I would like to state that we are not in a relationship. I do however have the biggest crush on him (since middle school). I read everything possible about Scorpios and got to know him a little bit better and I am positive I can handle all of that as I am not really your ordinary Aquarius, however it became a bit harder to understand his motives after I confessed to him. We began to talk again a month ago; things went pretty well, we got to know eachother a bit more, got a deeper conversation, he told me about his family and even invited me to his house for a movie (though we never set a date nor it happened because he is busy with work and family). We spoke about the upcomeing holidays and told me that he will spend his New Years with his friends and the mountain side. His friends are bringing their girlfriends and he asked me if I wanted to come with him. I refused of course. already had plans with the family for both Christmas and New Years. There was a very cold and rainy day after I left work and I messaged him in wich he replied to quickly get home, drink tea and go straight to bed.

I confessed my feelings for him, his reply was something that I expected. Telling me he is busy with work, that he will not have much time, the we will only be able to see eachother on Sundays and everything. Now, I would never ask him to change nor want him to change because I fell in love with him the way he is now, the strong-willed person that is not afraid to follow his dreams. However he responded that he does not know what do to.

He almost never texted first ( only once or twice ) and usually I would wait 3-4 days before texting him again. His replies would sometimes be short, sometimes long and sometimes I would get only seen. (wich would make me feel utterly annoying). But now, I really do not know what to do. I sent him a text two days ago and I quote "I would pick your storm, I would pick your rain and thunder over someone's else sunshine every day". Maybe it was to much, but I wanted to be honest. Still not reply, almost the third day. I am thinking that maybe that was a warning, that he will not always be there and wanting to state it from the beginning. I am thinking that he may care about me in that way. But I really need another perspective on this so please do help me understand better.
