Is she over me is it over?

I am a bisexual woman,she is a lesbian,we are long distance and have been talking for a long time.Recently we got into a fight over a jealousy thing,it was my fault.We then had no contact for 5 days and she contacted me first.I then said i miss her but she is so cold,she does contact me but it is not like it used to be ,she is distant,slow and sometimes she will be romantic like before but other days very cold.

No idea what to do anymore
