Someone please tell me what to do

So I really like this guy in my school and he is a senior and I'm a junior. So far we have been snapchating like having conversations for about 24 days straight so I thought it was finally time to tell him I like him. Last night I told him I liked him and he replies with "Not that I don't like you but I'm not looking for a relationship" so I was like oh okay but it was getting late so we have another conversation and than I said goodnight and he replied with "goodnight". Every morning when I send my streaks he scb saying something but today he didn't he left me on read. I'm really sad now because I really like him but I understand why he doesn't want a relationship because he is in the army so he only comes back home for school and those goes to georgia for 4 months every summer. I still don't know what "not that I don't like you" means does it mean he likes me or he doesn't like me? I don't know what to do because ik this is going to be awkward.
