PLS HELP...MY HEART IS SO PAIN!!!?

I know this is going to suck to hear, but it really sounds like he was planning to move on anyway, and he was just looking for the smallest excuse. You didn't do anything wrong. He just wanted to go. I'm sorry your so hurt, and there's nothing I can tell you that's going to keep your heart from hurting right now, but I can tell you that something better is around the corner for you and you just have to stop trying to fix this broken thing and let it p. It's not your fault. It's just time for you to move on. And you'll be okay.
