Boobssucker, I assume you both are or were in a committed relationship. And as it could happen with in any relation like married couple or between the friends or siblings or even between parents and children such fights happens all the time.
In a heat of moment one utters the words which he/ she really didnt meant to say .And if the person to whom such a woeds are uttered is a matured and understanding enough he/ she does not minds it and should not mind. because invariably in such relationship both partied loves each other that much is very much clear.
Here now you saying that you used the words for her which you should have never used. but still you have felt very sorry and expressed your apologies. Still she has not relented . But brother the pain you have given her is too fresh to forget it so quickly. It will take some time to get over the inflicted wounds. But definitely they would .Be sure of it. And just keep saying sorry to her by sms if possible. Try to meet her in person and tell her how sorry you feel and how much fool you have been to use such stupid words for her. I think everything will be fine in few says
best luck
