I think I really screwed up can this be fixed.....?

Oh my when your angry your angry like you say what comes to mind in a second.You did screw up and throwing apologies back and forth isn't going to make things all better for a 24year old you should have acted better and had a mature adult conversation this sounds like teen drama.You need to give her space now she's heard what you've wanted her to hear now just let her have her breathing space and when she's ready to come back and talk to you about this she will.
