Nothing hurts more than a broken heart. Give this a read and it could inspire you.
There Is No Shame In Loving Too Much
You put your heart on the line. You were there willing to be there for them. But they let YOU down. When you hear stories of people sacrificing themselves for love, you think of how amazing THEY are, not the person they loved. You deserve to be PROUD of your ability to love. Your love could move mountains and change the world. Their selfishness is what causes pain and regret. Wear your wounds like battle scars not damaged goods.
Find a way to release your feelings in a healthy, positive way. Do not allow it to inflict on anyone else's life but improve their perspective. There is a reason most of the best music/art/writing comes from heartbreak. This is a time for you to become everything you've ever wanted to be. And that's fucking amazing.
Don't Rebound/Run Away
If there is one thing I regret more than anything, its sleeping around to get over my exes. Trying to fill a void is repression. It will take you years to get over real love if all you do is have casual flings and it will emotionally damage you. Face your pain and all your fears. It will hurt like a motherfucker. But once you've faced that pain, you'll be surprised that you won't be scared to fall in love again cause you know you got through it once already.
Don't Stay Friends
If they can be cruel to enough to break promises then they are not friendship material. You still want them in your life because you still love them at least a bit. They want you in their life because they need you but don't love you. They need you because of guilt, regret and self-pity. Not love or friendship. Do whatever it takes to get as far away from them as you can.
What You Feel Right Now is Reality Not What You Felt in The Past
This anger, pain, sadness and regret is what this relationship gives you now and will always give you. Remember the good times for your own happiness so you can live a life that you feel was worth it. But that person can no longer offer you that happiness. His/Her love was CONDITIONAL.
People Like Me Are Waiting for Your Kind of Love
You aren't ready for a new relationship, trust me. But when you are... know that there are attractive, magnetic and irresistable people here to offer you the best kind of love like you dreamed of having. Tears don't make you ugly but we've been through that pain too, so we recognise beauty when we see it. People like you GLOW. You don't even see it and your ex can't deny you THAT SHIT.
There's more I could say. But for now, it's important that you figure out the rest yourself. It will feel better than that love ever felt.
