Shower seal (and wife) problem

I'm trying to re-seal an existing shower - where the tiles meet the tray.

There is a gap of 8mm between the shower tray and the bottom tile. I have filed this with sealant, but there is some movement in the floor and the sealant stretches and fails.

I am thinking of putting tile grout in this gap then sealant over the grout. But I am worried that tile grout so near to the shower tray may not be a good idea. Will it crack if the shower tray moves?

Cannot use a seal strip because my wife says so.

Only other idea I've had is to push a narrow plastic strip into the gap then put sealant over the gap- hopefully the plastic strip will stop movement. The plastic strip should be less likely to crack.

any advice?
