Mixed signals. what do I do?!

I met this guy on Tinder- yes I know what you're thinking- it's just a hook up, but it wasn't. I've been on the app since my bad break up in January, but never really used it. He's super sweet, I've spent the night with him a few times. We actually hit it off because of his love for Greys Anatomy. Here's the catch. He's in Illinois for school. He lives in Florida and doesn't know what's going to happen after college. (He's hoping to get drafted for baseball). Well, your girl here caught some feelings she was trying not to catch. He said when we first started talking and getting to know each other that he's not sure what he's looking for- that he's just going with the flow and will let what happens, happen. He's scared to date because the last girl he tried doing long distance with was psycho and wanted to control everything he did. I've been avoiding him the past week because I just don't want to get hurt. He messaged me last night because he wanted me to come see him, but can't due to bad weather coming. I do like him though and am just trying not to get my hopes up. He treats me like we are together though- then other times he's reminding me that he may not be here in a year or so. Like he doesn't want me to get used to him being around? So, I just don't know what to do. Do I ask him what we are. I know guys hate that question. I do not want to scare him off. It's literally consuming my mind lol.
