<human>: Can you condense the text into a few key points?

So my GF has been lucky enough have won an educational trip through work and has gone to Jamaica for a week. Now she seems to send me a text on WA and then when I reply she'll either completely ignore it or reply like a day later. Now I don't know whether to ask if something is up or whether to just start doing the same to her or just ignore her. She also lied to me the other night saying her WiFi ran out, but, saw that she uploaded a picture to facebook a few hours later....? Is she just doing this to make me miss her? Tbh it's more just pissing me off.
<bot>: GF has gone to Jamaica and not really talking via text do I start giving her a taste of her own medicine or ask if something is up?
