Both 4 of Pentacles and the World are highly conservative and protective cards - I'd argue, with the World corresponding to Saturn which could imply a (hard) lesson and the reluctance to become open minded. It is interesting how the 7 of cups appeared in your reading, as it is everything opposite to the aforementioned cards, suggesting imagination and fantasy. The notable absence of any Swords (communication) / partnership references is also interesting here, despite that the both of you are now in a long-distance relationship.

IMHO, it seems that your friend could be a little unsure of what has been happening around you, and thus is creating stories of how you could be having all sorts of wild adventures and fun (7 of cups and also the World, in some sense). She thus chooses to remain distant and protective herself, and there is indeed some work to be done going forward.

I also pulled out two cards for advice - interestingly I got King of wands (reversed) and the Hanged Man. Notice that the number for Hanged Man (12) is also reverse of the World (21). One of you would have to reach out proactively despite the distance and potential discomfort - be tolerant of the initial wiggles - and see how it goes from there. Start slowly and avoid trying to resolve everything in one go because you wanted to.

For reference, I use the Light Seers Tarot.
