Most Helpful Girl
LDR are One of the Hardest to Have and to Uphold here, dear, and it takes two special people to make the effort and take the patience to work together as a team to keep this going.
You seem very determined and your heart even more so to win her back.
Send her an email and pour out your heart. See if she responds. If not, then you yourself will know when it is time to lick your war wounds and move on, no one can tell you.
You might also want to tell her that when you have the chance, you will fly out to see her and really mean this. Face to face as well is very important in LDR and without it, it can go dead real quick in the water.
Good luck. xx
