Most Helpful Girl
I just recently went through something similar. Although I'm not 1000% better you have to realize certain things doll.
First you have to be honest with yourself, don't fight the way you feel, let yourself cry and do whatever else it is you need to do. Write your feelings down, cry, whatever it is you need to do. The worst thing you can do is deny yourself the ability to feel these things, otherwise you will be stuck in the same state forever.
Then you need to let yourself let go of that relationship, just keep telling yourself that it didn't work out because it wasn't meant to. You also need to remind yourself that it doesn't mean that you aren't worthy of having someone wonderful. He just was not that person and while you love him now, you were only meant to love him for the time that you were allotted to.
The next thing you need to do is have a talk with him, a private, honest talk. Tell him how you feel. You need closure. You need the source of your pain to hear these things. Make sure he understands how it makes you feel, why and how it hurts. When you honestly get it out of the way no matter if he is apologetic or a complete asshole about it, you take a deep breath and you walk away. I mean, literally walk away after you said what you had to say, take a breath and walk away. Enjoy the wind in your hair, the sun on your face, the green of the trees, whatever it is that's around you take them in in those moments, the good things. So whenever you think back to that moment, it won't be sadness , it will be content because you will remember those other things around you at the time, the air in your lungs.
I'm usually military about these things so you need to make a decision and stick to it. DO NOT STRAY, do these things like your life depends on it, not his life, yours.
It's the only way. When you get in front of the mirror, make sure you tell yourself that you are beautiful and you deserve better. Even if you don't believe now, say it out loud.
