Just do what your heart tells you.
If you take her with you, maybe you will break apart soon, if you leave her maybe this could be your own selfproof that you deeply love her after you come back.
Or, you could even lose a precious partner forever.
If she is still there when you´re back, she´s the one, boy!
If she is not, then nothing was lost.
It is just the infinite world of possibilities opening in front of you, congratulations. Anyway, just do it!
Check the voice of the heart, not the brain.
If you think you can or if you think you can´t, you will allways be right.
(H. Ford)
You are not going crazy, you are just starting tu build a life upon your own choices.
Good luck in your decision
