Most Helpful Guy
I'm in the same boat just the other way around. My girlfriend broke up with me out of nowhere about a month ago to go out with another guy & I thought we'd be together forever. She didn't blame me, just wanted to be with a new guy.
I've had a good mix of good days & bad days since the breakup. I'm in college & I know it's not manly to admit but I've had days where I'm just so sad, unmotivated to do anything & get depressed. Don't let yourself do what I do. Don't get stuck feeling bad for yourself. I bet you're a great girl who deserves someone who truly cares about you & will always have your back. You have to be strong & make yourself spend more time with friends & family & realize they can be very helpful to you.
I recommend trying to avoid contact with him & give you both your space. It'll take time, & it's taking me time... But you will get better...
