My long distance girlfriend and I just got into a fight can someone please help :(?

Okay so me and my girlfriend were talking and i told her that i think maybe she should date someone there so that way she can have someone to love and care for her, since im so far away. She said that there were only 2 guys that she would be with thats there with her but they have been close friends since 5th grade and she doesn't want to ruin their friendship. I told her maybe you should just try and be with one of them since you have feelings for them. Then she said this exactly ( we were talking on facebook at the time ) why do you always say this crap trey ? you act like you never wanna be with me... ughh just alright whatever trey i'm getting off here bye. Now she wont talk to me is there anything i can do to just make things right again because i do love her a lot. I'm 16 and shes 15. Thank you for your time
