How to get wife to be financially responsible she sets a poor example for teen?

I deeply resent my wife for only working part-time. She is very generous with my money. She spends 20 dollars a week on coffee. She robs me blind going to the post office to see the Halloween graveyard. She uses double coupons and buys subway and other restaurant meals which are still too expensive.

I dislike the dog staring at me. I asked my wife to rego.e it because it's that annoying.
She should be cooking from scratch. She said she is uncomfortable cooking because I complain so much and rush her around and bombard her questions about how long is it going to take to cook.
She took my daughter for ice cream after she got dumped by bf and abandoned by her friends.
I can't say anything because she takes care of autistic teenage daughter the entire time she is here i can't seem to connect with her. I'd prefer she stay in her room and not make a sound or speak at all. But no she has to talk my head off about fornite and skippity toilet.
