Should I? Should I not?

I'm so confused...

I've been basically talking to this guy for over a year now and we both like each other. Problem is he doesn't want to be in a relationship with me..just yet. His reason is because of wanting to focus on school (which he is super close to finishing). But always says that we will be in a relationship some day

It's been over a year and I've been beginning to think it's never going to happen. I've tried to tell him how I feel and it seems like I can never really get answers out of him.. should I even wait anymore or lose all hope?
