If she decides to come back to me that is definitely the plan.
Are you even listening to yourself?
You can put your life on hold forever, totally your choice. Just know IN ADVANCE that it may be all for nothing. If that's OK with you, fine. Only you can answer that.
Meanwhile, I have to say it:
"There is such a thing as stupid faithfulness." You can read into that whatever you want...
It makes just as much sense to NOT wait and still get together later if you two end up in the same place and not committed to others. Staying "together" when you're actually not is the definition of "avoidable frustration."
My recommendation: Remove your "titles" while you're still friends, then both of you do what you want. You're apart so that's fair anyway. If nothing better happens to either one of you, you can start again later IF cross paths in solid way.
IF.
Meanwhile, stress is gone, humor is back, playfulness is back...
