So what if there's no back...

You don't need to. Part of you will always be everywhere you've ever been

Then you continue to move forward

If that happens, it's probably because you don't feel the urge to return. (You're not one to shy away from dreams after all.) So you probably found a better place to stay then.

Not even as a tourist? To completely sever that contact with your past? For me it would be quite a wrench.

They’ll still remain within you. To revisit- or not- as needed.

You go back home I think it be better
