Am I being immature?

Thing is simple. I am sure about my feelings for this guy in a 80% but he can't admit anything yet, he tells me to be pacient. (I'm trying). But shit is so scary because I'm so in and I'm not sure how in he is... I don't want to adress the conversation again cuz he always tells me the same thing "be pacient with me, it takes me time to open" (know that we have been dating for a month already) and I don't want to be intense and annoying. So I decided to distance myself from him a bit. Be less available. I can't be so over him meanwhile he may not even feel the same. It's unfair and scary. He will either notice it or won't give a fuck.
