Ysbeertjie, take a look at the entire thread. You can see the past you, the efforts you have made, who tried to contact who and who left who in the dark. Is there a 4th time? I dont know, this could go on for 5th, 6th time too, but small chance that it wont end like the same old story. A relationship needs trust, commitment and understanding. Your trust is already shattered, there wasn't any commitment.
If your best friend was in your situation, what would you tell her? I bet you would tell her to 'move on,' and mean it. Like everyone here who put care in their answers, give yourself a chance. "I will not think about the past" should be your FB status now.
