HITCH HER OR DITCH HER??????

I'm 21 and this girl I met like a month ago is 23. We went to a Cubs game once and we've been talking on and off now. She recently went on vacation to CA and stuff with her friend named Biff and she hasnt texted me in over a week. He had Cubs vs Dodgers tickets for 2 games right behind home plat. I saw the pic on her facebook. She looks like she had a good time. texted her last night when she made it back to Chicago. I asked her why she wasn't talking to me anymore. She said she was really busy and stuff. I found out she still has feeling for ex about 2 weeks ago, but apparently shes getting over him. I told her that I missed her and her response was yah lets hang out again and i said ok cool! Well then she said she was going to bed and say good night sweetheart! She never says that to me. Wtf is up with that? I told her once before that I liked her. She said that she was glad that I told her and she would like to continue talking and hanging out. Am I toast?
