At the risk of being a little bit of a downer, spend a little time grieving what you’ve lost before you move on to other things. Even if if didn’t work out, even if you ended it, it was still important to you for part of your life. And take the time you need–some people move on quickly, some people need a little time to figure out who they are again when they’re not with someone. There’s no “right way” for everyone, but I do like the advice someone added.
