The pages (if not representing people) can show the beginning of a new phase in something so the Pentacle Page could show the beginning of a new phase in a relationship - the relationship could be about to become a physical one.
I think that it could also show a new committed attitude to an already existing relationship.
The Page of Pentacles is a practical, down to earth type of person. He loves nature and the 'outside' and is filled with curiosity and wonder (just look at the way he's usually depicted gazing at his pentacle).
He's trusting and so yes, I think that in a love reading he could signify trust.
I would say that he shows someone with a commited, trusting way about him, someone who is willing to work at a relationship.
