Guys what would you do?

she was 5"7, i was 5"8 when we started datin a year ago. during this year, she had a 3 inch growth spurt so now she is 5"10. thts two inches taller thn me n thts really ****** up. I know i'm being shallow, but this is a real issue for me, and i don't know how to adjust to it..solution, we have to break up, but its hard coz we have shared soo much. i jus dun wanna hurt her..any ideas??
