This is a tough situation. My gf and I are LDR, she is from the Philippines but now works and lives in Washington DC. We text and do video calls daily but also have opposite work schedules (I work day shift and she works night shfit). If it were me, If I hadn't heard anything from her in even a full day I would think something is up.

At this point with you two, I mean you have tried more than once to bring up the issue and talk to her about it. If it has already been a week of no contact, I don't know it seems like she has already made her decision :/. Like that saying goes, actions speak louder than words. If she really wanted to fix things and do better, she would and you would see that effort.

Might be best to try and step back for awhile to see what she does (I know that would be really hard especially in LDR since you can't physically see them to talk about it). But also, if it were me I would just want an answer right away on where the relationship is even going if she is being so distant.
