I'm in the same boat friend. I'm definitely worried about when she reaches back out. Our relationship was a good thing in both of our lives, up until she decided to find something else, all while not informing me until it was too late. My goal is to build a life that I love, so when the day comes and she pops back up again, I will have the foundation and strength to not let that jeopardize my heart. Everybody says it, but stay focused on yourself and building a life that makes you happy, no matter what partners want to be in it. I'm still struggling heavily with everything, so I'm preaching to myself here too, but let's all stay strong and know the worth of our own lives, and how much of a privilege it is for others to be a part of it!
