Are you working on the phone and it's not going back together correctly, or did the screen just start separating on its own? Has anything happened to the phone recently such as being dropped?
If it's the former you'll probably need to add some pictures so we can see what's going on with your phone since there's no way we can tell what's wrong just from your description.
If the screen is coming off by itself, the first thing to suspect is the battery; if it's swelling that can push the screen away from the frame. You'd have to open up the phone and inspect the battery to be able to tell for sure.
