<human>: Hey everyone,

A few days ago my girlfriend of 5 months decided to end our relationship. We met up yesterday to finally make it official and I got the closure I so desperately wanted from it.

My issue is that this girl was my first true love and I saw a future between us, it's so hard for me to understand how she could end something so special. 

My question is for people that have been through breakups before, especially your first longer term relationship, how did you handle it all? How did you cope from getting your heart broken for the first time when it hurts so bad and is constantly all you cant think about?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Girlfriend of 5 months broke up with me and broke my heart, how do I move on from this? I'm so lost :(
