It never gets easier to move on even if you've had your heart broken by several girls over the years. It sucks everytime. The truth is, if you did everything you could do, treated her right, did everything right, and she still dumped you, then you just gotta come to terms with it just wasn't meant to be any longer. And, you gotta know that another girl will appreciate that stuff the other took for granted. Eventually you will wonder why you even loved the girl, once you fully heal up, and once another one gets your full attention. It does take time and best thing you can do is keep busy and focused on yourself and taking care of yourself.
