Hi Greg
Phew! lotsa decisions though it all seems to hinge on the RAF. You seem to have your heart set on it. Have to agree with H, if someone loves you they don't give ultimatums.
I have a mate whos about to marry her soldier fellah, just before he goes to Afghanistan and supports him all the way. tbh, you'll both be too busy with career/study to pine too much and she will branch out at uni as you will in the army. You will both grow in fantastic ways.
Is it worth changing jobs for such a short time, and to one you don't feel comfortable with either? If you can think ahead to happy possibilites in the RAF, it will make work pressures more bearable
Opportunities fly by very quickly and the best ones don't give you much time to think, but give you the best rewards. Go for what makes you happy, be adventurous while your young enough and fit enough. If you and emily love each other and its meant to be, it will work out for you both
Good luck whatever you decide! lol
