Will divorce take place if one tells someone that he will divorce his wife?

Q: Please advise if talaaq takes place in the following incidents:

1. Telling my wife that we will get divorced.

2. Telling my brother in law and wife that I have decided (meaning that I have decided that I want to and will divorce my wife).

3. Telling my father in law that my wife and I both decided that it is best for us to get divorced.

4. Telling my mother that there's no other option (meaning that there's no other option for my wife and I other than getting divorced)

Washing a soiled carpet

Q: I am having trouble learning how to purify a carpet. I honestly feel like I have transferred filth in so many places, it must be likely that my salah are not counting. What is the difference between a thick and thin carpet?

I put water three times on impure cat vomit while drying (not completely) with towels in between. But the carpet is thin enough that some water gets to the bottom if I saturate it with enough water. Did I do this incorrectly and now filth is transferred everywhere since later on peoples feet touched that wet area?
