I too like most members here in the forum is currently going through a breakup. Its been 2 weeks today since I last contacted her and just like a little devil inside me wants to pick up the phone and call her/text her again. I know that will do not do good as I'm trying to leave her alone. So i'm sticking to the NC rule.
I would say: How can you just walk away from our 2 years relationship without talking, does it mean anything to you?
What would you like to tell him or her? What been building up inside you that you just want to let it all out. Before you think about picking up that phone calling or texting your EX. DO NOT CONTACT him/her. Just put in post it here.
