<human>: Can you condense the text into a few key points?

We broke up when college ended for the year, as there was a lengthy distance and we wouldn't see each other for the summer.

We were adamant we wanted to remain friends.

A month after the break up we stopped talking for over a month.

I tried to talk to her on facebook but it really seemed like she struggled to talk to me, eventually getting replys days later.

When I asked her about this, she just just had a blow up and started arguing with me.

A month after the facebook argument and 3 months after seeing her , we're back in college and I'm meeting her for coffee soon. I saw her around today with a mutual friend and she couldnt say a word to me after I started conversation.

What can I expect from the coffee? why did things quickly go from good friends to hating my guts. Can we be friends out of this?
<bot>: why do things quickly go from really good friends, to I never want to see you again get out of my life so quick, even if the break up was mutual and ended well?
