Why would he save our snapchat conversation?

So this guy I have had a crush on for a while now I finally told him I liked him, we hung out/hooked up and he told me he is happy to have something that feels real and right and how he feels like he can be his true self. We hung out again but this time he said "it's not that I don't have feelings, I'm just not sure if I'm ready for a relationship" but he still let me hug him and still talks to me everyday and still ok with hanging out. He actually saves every single one of our snapchat conversations but I'm just a little confused as to what this could mean. Does he like me and is just scared? I've never had a guy save entire snapchat conversation before. Any outside opinions are appreciated.
