Maybe it’s because she wants privacy from her followers, which I‘d totally understand.
And that's totally understandable, but do not lie to your audience about a solo trip then. Just say you've been away and don't mention who with? It's the same as saying "I've lost all the weight with diet and exercise" but secretly getting a tummy tuck.
I'd rather think that she met someone there as that's one of the best things of travelling alone than think that she lied for content.
