<human>: Can you give me a shortened version of the text?

We had planned a great four day weekend together for valentine's and I had had no intuition this was coming until Sunday night. 
She told me her priorities have changed and that she needs to find out who she is outside of a relationship. Doesn't want to be half invested in it because it's not fair to me. These are all reasonable point but the disconnect is that about a week and a half ago we were discussing getting married and I had solid plans to move to her city by the end of this year. We haven't totally decided yet but it feels basically assumed. 

She does not think it is a good idea for me to still fly out there but I can't swallow just ending things without ever seeing one another again. Especially since it is so sudden. I have an old roommate who lives close to her that I could stay with if I go out but I'm wondering what advice you all have for getting over something like this and if I should fly out or not (tickets are paid for). 

I have already gone on two long ass runs to clear my head and barely slept 40 mins last night. I'm sitting at work but I can't focus on anything and I feel lost.
<bot>: long time girlfriend blindside break up after 8 months of long distance, still have a trip and vacation from work planned for this weekend. What should I do?
