There also is a height difference. The top of the tiles comes even

Do you mean to say that the finish surface of the tile is in the same
plane as the finish surface of the sheetrock? That makes the
situation a bit more difficult.

Normally, the surface of the backerboard is in plane with the surface
of the sheetrock, as both are 1/2" thick and applied to the studs.
Then the tile projects out further by its thickness. The transition
to the sheetrock is accomplished by having the tile extend over the
sheetrock/backerboard joint, with a bull nosed edge to provide a
gentle curve.

I don't think you want to use a bull nose in your situation. You
could try just running the tile up to the sheetrock, then you'd have a
tricky plastering job to make the edge of the sheetrock neat and
presentable. Or you could try to use a thicker, decorative tile with
a built in rabbet to cover the rough edge of the sheetrock.

Or, butt the tile to the sheetrock. Then put a line of smaller,
decorate tile on top of the joint -- sort of like a verticle chair-rail.
