I must be stupid

So the first releationship i find in a year and a half is over. In less than 3 weeks from the beginning of us seeing one another, Olivia has said she dosnt want a releationship. Now only a week before she was all over me, kissing stroking, and various other things in wild abandon to me. We spent 3 months learning about each other over Skype, countless nights wishing we were with one another and then poof, its all over kids. Why? Honestly why the fuck did this happen?  I must have been so stupid. Because I thought I could win her back only to come home last night, to see her laid up on my room mate. And my god was I angry. I nearly lost it. Actually I did loose it. So much rage growing within me I couldnt believe it. Hurt, betrayl, shame…..I had no idea what was going on. She acted as if she had done nothing wrong. How? What can I say? The first girl i say I love you to in a year and a half……gone. Because SHE some how dosent care about me ………WHAT THE FUCK! This has been a horrendous week people.
