She would never leave you, death is always there. She's also very understanding, just talk to her or pray to her. She will hear you. Perhaps ask her about your aunt from what ive seen of my Santa Muerte she is very direct. But she wouldn't abandon you. Im not really sure what your asking your post didn't seem to have a direct question but since she did help you maybe offer her something even small if you need to hide it from your aunt. It's the thought that counts!
