Well you should not put her over your knee and make her ass red. That is called topping from the bottom.
Your sub you know what she hates but do use that as a punishment.
Or utter those words that cut through any sub

Punishments should be just that punishment for doing something wrong. However the punishment should not be something that you would enjoy. If you enjoy pain the anything pain inducing should be avoided. The words disappointed in a certain sentence could suffice

Should really discuss this with your dom as you coming here moaning by advising that you demand this that and next thing is very poor form.

Sadly you have to bite the bullet and move on to someone who would appreciate you not the gold digger that you were involved in.
It is not investment it is throwing your money away and since you cannot fund her lazy ass she giving you the cold shoulder. Face facts and move on

Make up your mind.

And there was a thought running through my head about public transport. Wait for the bus and next thing three buses come at once

Lol the saying .... jack of trades..... master of fuck all
