In short, although you are not bound to make the whole (Nafaqah) spending that includes house rent, bills, food, clothes etc. I see that you should send her some pocket money.

 

A Muslims should be generous and she is legally your wife on papers. I do recognize that the marriage has not been consummated yet but this is part of showing her how much you care and it will strengthen the relationship insha Allah.

 

Almighty Allah knows best.
