First, I want to say that I am sorry that you have experienced this heartbreak. It's a very crummy feeling.Second, I would invite you to look at this as an opportunity for you to find happiness for yourself that doesn't rely on another person. As wonderful as any relationship can be, it's not healthy to base our personal happiness on someone else's presence in our lives, especially because we never really know how long they will be there, or how involved they will always be. Even your best friends today may only talk to you once every few months in the future as you all grow older, move away and build your own lives. Dependency on another person like that hampers our own personal growth, which is why when that person leaves we feel so lost and unable to cope - they were our coping mechanism.While I'm sure you enjoyed his company and the love that you two shared, trust me when I tell you that you will be alright without it. I have personally only dated one girl. It lasted 4 years, and when we split up it was soul-crushing. Given enough time though, I returned to doing the things I love, enjoying my hobbies, spending time with friends and family and being able to put all my energy and time into exactly what I wanted without having to worry about the proverbial ball 'n chain.Give it some time. If you can, talk to a counselor about your feelings - mine helped me a lot with my breakup. In the meantime, go back to your hobbies and enjoy the time you have!
