Problems With Ukrainian lady friend

I am 61 and have been communicating with a 52 year old woman from Dnipro for 5 months

. A  problem has surfaced in the last week. Her cousin from Odessa rang her last week saying her cousins son was badly burnt in the Odessa College fire.  The woman has been in Odessa  for the last few days. The boy had to have an operation on his lungs and my woman had to pay her entire monthly salary for part of the operation. The woman and her cousin have had meetings with City Hall to seek compensation, with no luck. They have also sought donations from friends and family but are still unable to raise enough for the boys short term care. The problem is last night my woman asked me to deposit money roughly about NZ$800 into a bank account. I told her I wasn't prepared to send her money as we had not met.
She has since gone cold talks but seems quite detached from me. Even though the relationship before was close and passionate. The thought she is trying to scam me has entered my mind. I am wondering what to do. Do I send the money  Just leave allow time for things to calm down. Or have things gone past the point of no return. Or are do I have to walk away as the risk of being scammed is too great.
Footnote we were supposed  to meet each other mid January here in New Zealand . She told me she could afford to pay to meet me and last minute told me she couldn't afford it after assuring me she could  3 times. After that I changed plans to meet her in Dnipro March / April.
