tub problems

Hi, I have had a few issues with 5 piece tub surrounds coming loose and leaking. The drywall always seems to get wet behind.
I have a dumb question. When I re-drywall, how far above the tub do I end the drywall? I have kept it about 3/8 in above but when I silicone, there is no backing because of the gap.
Any suggestions?

I always thought that the drywall came down to the lip on the tub. IMO it is always wise to apply a good coat or two of enamel on the drywall before installing the tub surround.

Perhaps that is my problem as the two that I have done so far, I only primed the wallboard. Maybe I should have painted also?

It depends on the primer. Most latex primers don't effectively seal the drywall. Oil primer should seal better but I think it is easier to prime with latex and finish with latex enamel.
