There are definitely some very remote areas where there is no phone service or Internet. Whereabouts is her home, and where is the 'province'?
This makes it sound as though she is trying to contact you - how does she always manage to pick a time when you're not there?All I've got back is the same I've been getting all week, a left message on messenger. Just says, "Are you there?"
Perhaps there is another guy in her life - and that restricts the times when she can get online?
I guess that if you cannot get to talk to her then the relationship is over.
However, filipinas have a very different attitude to relationships compared with most western women and their reactions may well be very different to anything we're familiar with ... there may be some logical explanation.
