I start contemplating suicide at this point. I love her, I love her friendship, I just don't love... whatever this is.
Back to your topic... I agree with a lot of the other points being made here. You need more low-maintenance friends. Ones with whom you can not see for months at a time and then pick right up where you left off with no problem or accusations of being ignored. Most of my friends fall into this category now.
If you are conjecturing on how you will be able to handle a long term romantic relationship based on this information, then I still think you will be fine. You will just need to find another independent person to be with for the long haul. Someone who can water and feed themselves.
