My Friends Wife Wants To Put Me In Trouble

My phone rang as I was going about my business in my office and trying to escape the tedious drawing I was doing. I looked it up and saw that it was an unknown number, so I ignored it and kept working. The phone rang again I still did not pick. About 15 minutes later a text came from the same number that she is Mr X (my friend) wife that if I’m free I should call her back.

Immediately I had to call back.
She picked and start by apologising for calling but she couldn’t just help it. That they are very broke at the moment even their little baby food is finished and no money to buy it that she had asked her husband to call

I was not having much at that time so I sent 20k to his account only for my friend to call me later to thank me and also indirectly warn me not ever listen to such call from his wife.

My concern here is, why is that the same person that asked me not to tell her husband be the same person to tell her husband or is she trying to cause problem between us?
