<human>: A year ago, I began a short, troubled relationship with a girl from my school (my first love). It ended 3 months later (this march), then I tried to just be friends with her. 

Worked well for a while, then we hooked up again several times but not in the same way.

I know that I couldn't ever take her back. We have built up some serious problems relationship-wise and we can definitely not work them out in order to get back together again. But she still loves me and deep inside I still love her. (When I heard that she is flirting around with a new guy, I was simultaneously happy and raging with jealousy at the same time.)

I know that to fully get over it I need to separate myself totally and work on it on my own.

Thing is, I have to see her every day at school. I tried not having any contact, but if I still see her in this time, it's killing me, especially after a few weeks.

There is a lot of tension on either side, whenever we hang out as friends it mostly ends in hurtful arguments out of nowhere, and we both end up miserable.

I need to find a way to still be friends with her, at least until summer when I graduate and don't see her anymore. Then I can start getting over it again.

Can you provide a brief rundown of the text in within 3 sentences?
