We were together for 7 years. Broke up 2 days ago. How do I get over him?

I am sorry you are going through this. There is no easy way but to be strong and think of your own self respect. You are still very young and there will be many more loves in your life. Try to keep yourself occupied and busy with hobbies you enjoy, go shopping or clean the house. Try to find someone you can confide in to talk it out. Best of Luck I know from experience it is hard to do but keep your chin up and you will get over it, right now you may not believe it but you will!
