So your last good contact with her was on Sunday. She's away on holiday end of this week and is probably busy or not overly in the mood for doing anything given that she's going away soon.

Again. i think your reading into this way much - stop overthinking it.

She's away to go on holiday - she doesn't have time to see you just now, no biggie. Leave her be. Text her a few days after you know she's back from her holidays and pick it up again.
