How can I move on, when I'm still in love with you

It hasn't really occurred to me how little I think about you nowadays.
Obviously, in February when we got together, I never thought I'd be listening to songs and hurting, this used to be our song as on the first night I met you, we met on the corner of the road at the last summer carnival, and it wasn't intentional.
It wasn't until last night that I dreamt about you, but you were too far out of reach, and I realised how much I am still in love with you.
I guess it's sad really.
You're in the navy, so out of reach, and I just.. can't have you anymore.
