she said she has lost feelings for me?

Two months ago this girl came in my life, she's on my track team..she asked us to exchange numbers and we did I never texted her but she started texting me towards the end of November and we went from there. Things have been up and down between us over the last two months like after the first two weeks of us talking she says to just be friends and I said OK but the next day she texted me and we made up, and we got into another fight a week later I thought things were over so I didn't text her for 2 days but she texted me saying she missed me. After that she showed a lot of interest..we are in college and we just got back from break last Saturday and before we got back we got in a fight but we made up again and she x a me over the Saturday we Returned and we had sex for the first time, and had sex the next day and had sex again on Thursday morning..she had invited me for a double date with her friend on Thursday afternoon two weeks ago so we go on the date and she's acting distant and after the date she texteditor me 2 hours later saying she only sees me as friends and she has lost her feelings for me and wants to stay friends and I said no I won't be your friend..so on Friday we talk IN person and I tell her I won't be her friend because said he really hurt me..but she doesn't even care she was getting drunk and high last night like nothing happened while I was in pain alone, I havent made any contact with her since Friday, but I see her everyday..what do you guys think
