Is it OK to show up at your gfs house uninvited if you have been fighting and she has slowly faded away?

I never showup unannounced. However I HAVE to talk to my girlfriend/ex girlfriend?(I don't even know at this point) We got into a big fight over something right before I left this week for a business trip and during the fight she questioned our "compatibility" (meaning "you can't date me unless you agree to my terms and conditions"We have talked on the phone on a couple of occasions this week. Her words were "you're going to go up there for the week because right now me and you aren't working this isn't working... and when you get back maybe it will be different" I have felt sick to my stomach all week apparently she hasn't officially broke up with me. She wants us to discuss it all and she couldn't promise me we would still be together she said it depends if we can resolve the issue we had argued over. I can tell she isn't making any true effort to text or call me. I can also see she isn't treating me quite the same and she's really upset/questioning our compatibility. I haven't heard from her since we exchanged like 2 texts yesterday morning... and she ignored my text asking her to call me. I know this because I noticed she had been on Facebook messenger so I know she was on her phone and at least saw it. I need to know if she still cares about me and what's going on. Is it out of line for me to just show up if im still unable to get her on the phone by tomorrow?
