Hey everyone! I am looking for some advice on a maybe relationship? I don't know what to call it.

Here's some backstory:

On September 27, 2016 "K", my boyfriend of almost 4 years, came home from a 2 week long work trip around 11 PM and called it quits. I didn't get much of an explanation other than there was no one else and that he just wasn't happy with himself. We did have fights occasionally, but who doesn't? The day he left for the trip everything was fine. We spoke on the phone daily and everything seemed good up until the last couple days of his trip. He got really distant at the end. Anyway, a couple of days later we meet up and talk and decide that this isn't the end but that we both need to work on some things (his words). We make plans to fix things and then in November he drops a bomb on me - He's moving to New York - 2,000 miles away. Fast forward to now: We talk almost every day. Some talks are good and some talks are bad. But I can never get him to talk about us. Every time I try I am shut down. He says it's too soon and that, for him, nothing has changed. He says that right now he is just focusing on himself. But why drag me along if you don't have intentions of getting back together? I have asked him to come visit and he just says that it is to soon. I know he will be moving back here in June of 2018 and I have tried to find out what that means for us, but he never answers. He asks me for favors all of the time. He is so sweet one second and then a big ass the next.

Is he using me? Should I let him go?

There is a lot of love and a lot of history between us. But I just can't see us ever being just friends. Do you think I should just tell him that he needs to make up his mind and that until he does he needs to leave me alone? Or should I continue to talk to him?

I just need advice. I'm so lost and so tired of being hurt.
