I dont want to die alone...?

im a 20 year old guy, and met this 20 year old girl on facebook, and were both normal, and have eveyrthing in common. during the summer (2010) we texted and talked occasionally, and eventually talked on skype and wrote letters to eachother in the mail. we both stated we really wanna hang, and feel we can definitley relate. it was finals week for college students (im not in school, she is), and i hadnt texted her for about two weeks, and sometimes we go weeks without talking because we get busy. and today i texted her asking how finals were, and she said good and shes happy the year is half over. i said "awesome. glad you figured out the school thing!" because she was deciding whether to drop out or finish the year, because she hates school and wants to travel. and she never responded to that text, then a few days later on Christmas 2010 today she sent me a text saying "hello love!!! merry christmas!" before you think she wants to date me (not sure), she says i love you to all her friends, and after we texted a few minutes about gifts and stuff, then i asked (because we weve talked about talking on the phone a few weeks ago), if she wants to talk over winter break sometime... and she never responded. shes done this many times before where i'll text her something and she wont respond, than a few weeks or days later she'll text me, or i will text her and she'll respond.. .one of the two. so why is this?? could it be its christmas break? i mean she stated that she wants to talk on the phone soon and that she definitely wants to hang and travel with me, as shes also stated firmly... but it boggles me that she doesnt respond to certain texts....does she wanna hang or not?? did i ruin things?? everytime she ignores a text i send, and i wait a 10 days or so and text her, she responds liek nothing... i dont get it, did i ruin things
