<human>: Basically what happened was i had been going out with this girl i knew from high school for 3 years and it had been kind of an on and off relationship where we would breakup sometimes then get back together 2-3 days later but 2 weeks ago she finally said she does not love me anymore(she had said this before when we broke up). 

I told her i probably would not end up in a relationship for a while and she said she would not either. 

A couple of days ago i look on FB and i see that she is now going out with someone after saying what she said and im obviously mad at it because i still love her very much and it makes me wanna just go and cry myself to sleep and i can't cope with moving on even after my friends telling me its time to let it go (she was my first and i hers).

Summarize the given text in a few sentences.
<bot>: I was with a girl for 3 years we broke up and she got a boyfriend right away and i got mad and i cant move on for some reason. I need to know what i should do to forget her.
