How to fall out of love with somebody?

[Jacob]

I'm at a breaking point... No, my heart is broken. It's been broken by the same person twice.. I don't know what to do. I've never felt this way about someone and I know they feel the same they're just having a hard time revealing it. I've tried not talking to them, and getting rid of anyway of seeing them, unfollowing them on twitter and instagram.. And then all of the sudden as I'm getting ready to be over them, they just come right back into my life and I fall right back in love with them.. I see her and i get butterflies, and when i talk to her im just so happy, i dont think of anything, i just listen to her talk. And I enjoy every minute of it. Tonight I had my heart broken for the 2nd time. And I don't know if I should confront them about how I'm freaking getting destroyed, or of I should just let it be. I'm crying over this girl right now. I wake up and go to bed thinking about how beautiful she is. And yet I'm still trying to get over her. My question is, how can I get over her.. How can I get her out of my head? How can I just stop thinking about her 24/7 and being over protective(Not weirdly) and i need to know if i should talk to her about it.. just someone please help me I'm so mentally and physically destroyed.. Please, I've never cried over someone like her. She is everything to me.. But I guess, if I love her, I should let her go. But I don't know how..
