Since she didn’t tell you why she was breaking up with you it sounds like she’d just had enough of whatever was bothering her and didn’t want to work things out. If someone at least lets you know why they’re moving on, they’re giving you the courtesy of understanding their actions. It sounds like whatever her reasons, she has decided to move on and has done so, and isn’t interested in getting back together. The best thing you can do for yourself is to stop contacting her and stop keeping her in the back of your mind as a way out of having to move on.
Break ups are supposed to hurt and feel uncomfortable, but there is no shortcut through them. The more you keep lingering in her periphery the more pain you’re going to experience.
Long story short, I don’t think you can get her back because she doesn’t seem interested. I’m sorry.
I hope that helps. Let me know how you’re doing and I hope you’ll join me on Facebook, too. Here’s that link: [url][/url].
