First of all, hello.
Love is never a 50/50 contribution and it seems like you contributed much more than your partner. Neither is it 50/50 dedication, as you can see from the fact that he left you. Breakups are never easy, especially the ones that end a relationship spanning for years. Now it would be a good time to seek consolation from your family members and your friends. Get yourself distracted. I know you won't be able to distract, but TRY. Even trying counts!
I'm not old and wise, but I know a couple of things about relationships. Wait out for a little while and contact your ex, maybe he changes his mind and comes back to you. If not, then I'm sorry, but he's not worth anybody's love.
Try to find someone who will listen to you! It absolutely doesn't matter who will it be, they should just listen to you venting. It will relief the stress.
Be strong. Best of luck to you!

Time. That's the only way you'll move on. There's no magical spell or pill to get over someone. We all want to get over someone the day after, but it just doesn't work like that. Whatever you do, it's still going hurt for a while.
