BigGolem: Another idea is spending money on someone else. What if you could do a mitzvah together?
For example, if Purim is coming up, maybe you can buy some nice boxes for maschloach manos, and the both of you can go to a store and buy sweet treats to fill them up and give to a local shul or charity.
During other times of the year, maybe there is another way to pay this forward. She can invest her heart and creativity in this too.
The nice thing is that even if it doesn’t work out, your coming together for that date can at least still be a gift for others.
