I don’t get this whole thread.
As Jews who follow the Torah, we have a Shulchan Aruch that tells us what our priorities are for Tzedaka. Everyone should be following those priorities. The answer for the OP (and everyone else in the thread) is ask your LOR.
I feel for everyone without children, and I ask Hashem that they should be able to do so (both for physical and shidduch related issues). However, my feelings do not absolve me from following Shulchan Aruch. THey should not absolve you either.
