In a very messy situation?

ok, so after i went out wih my best female friend for 2 days, i still like her. but now, she just told me that she just said yes to someone, for some reason i couldnt hold back anymore. i was really mean to her, and now i regret it. she txted me 2day, saying she wanted to talk, but when i answered, she wont say anything back. ill admit that my jealously took over me for a second, but now i do want to talk to her about it. i really regret the way i said things to her, but now she wont talk to me :'(
