Carry over from my previous thread...

My W's D's birthday is Monday and I would like to give her at least a card and some money.

I have raised her as my own since she was 3 years old.

W and her D currently stay at W's mother's house. I know where they live, I just don't know the physical address to address the envelope.

Ive been contemplating texting W to ask if I could send D some money and if she can provide her mailing address.

W already knows that I know where she lives, she told me where she was going when she left me.

Thoughts?
