That sounds like emotional blackmail. There was (still is) a pandemic going on so of course people would not travel. You mention your family is still taking precautions, yet your partner dismisses these concerns and her message is: 'come or we're over'?!

Also why doesn't she come to you?? Why do you have to run to her?

It doesn't seem she wants to make it work but she wants you to run to her bidding. It all seems to be about her wants and her rules, not yours.
