My girlfriend and i had a big fight?

Well my girl friend i was talking we planed on getting married in the next six months, i needed my time to get things and my self in place, well we are in a diff country. she really wanna get married, she told me she could not wait until the six months, she kept wining in my ears so i got upset and told her that she must go marry someone else if she cant wait i told her she din't love me all she does is want to get married. yea i guess that was the wrong thing. She now i hurt her by what i said she now change her mind and is now reconsidering marring me, this is driving me nuts, i gave up everything to marry her. she says am immature and i talk 2 much and make everything be a prob. i don't know what to do now i really love her with all my heart. she says every day i say something that discourages her. what must i do am loosing my future wife
