Broken

My best friend of 6 years and boyfriend for a little over 3 years gave up on our relationship. After 3 months of migrating for school and deciding we were going to do long distance he broke things off n told me I was not worth it and we didn't make sense and that he can't multitask. I don't even recognize him anymore. I feel like he ripped out my whole heart and I can't breathe. And I'm angry. Mostly at myself. People always disappoint me and give up on me and it's frustrating at this point. He just walked away like none of this mattered to him. And I can barely even function. How unfair is that? That hurts. It hurts me even more that I love him still, I just can't forget him, he was my other half, my best friend. And now he's gone. Just like that. Strangers
