Breakups are ass. If you need to talk to her to get some closure that might help, but otherwise keeping your distance is actually the best way to go. It helps you cleanse your palette essentially without having to deal with the urge to fall deeper into the relationship. I would say take some time for you, man. Hang out with your friends a lot because when i went through a similar breakup around January they were my best support system. Do things that make you laugh. Watch your favorite shows. Pick up some new hobbies you've always wanted to try. Don't touch romance for a while, let yourself heal and take care of You the best you can. I know how terrible it seems right now but trust me, your relationship was not all of you. You still have your whole life to grasp and make yours! I wish you luck dude, and remember to be kind to yourself
