Answer 1

Short version: git pull is the equivalent of fetch + merge. You can --- by default --- only push "fast forward" changes, which means you've either merged or rebased your uncommitted changes. Contrary to what Blaine suggests, push has nothing to do with merging.

Longer version: You seem to not understand quite how Git works. As source control is an integral part of software development and you're using it, I suggest you read up on how Git's data model works --- and how to implement various workflows with it.
