<human>: We broke up a week ago after knowing her for 3 years and being together with her for one of those years. I'm absolutely crushed and I feel terrible, also I'm in a bit of a problem...  

We have been classmates for 3 years and became really good friends after a year. Basically i've spoken to her almost everyday for 2 years. We developed feelings for one another after a while, and with a lot of back and fourth thoughts, where we talked what would happen if we broke up and how this would affect our friendship etc.

This year has been amazing, and I don't regret one bit moving from friends to loved ones. We had amazing times together, we experienced being away from eachother over 6 weeks last summer, and got through it. We never had a big fight, I think much of the reasons why are our past friendship. Our breakup was calm, with her telling me she didn't really have those feelings for me anymore... She said, "I loved and love you, but those feelings aren't just there anymore".

However, we haven't had a conversation since the breakup, and it's killing me inside, from everyday to almost nothing. I've never been this low in my life before, and I just discovered this subreddit. How can i cope with this feeling?  

So here is the real problem, I'm as stated before classmate with this girl, and we have 5 months left of school. Our class isn't so big (20 pupils). I see her everyday and I can read and see the sorrow in her face, which breaks me up. I've several times needed to "go to the bathroom" to man up. So /r/relationships, what should I do in this situation?  

Sorry if this post is out of place, honestly it helped so much writing this.

Can you summarize the given text in a few sentences?
<bot>: Classmate with ex for another 5 months (broke up last week), don't know how to handle the situation..
