Buddhists talk about cause and effect. Don't you think it makes sense? Is there anything that comes out for no reason?
Do you pursue happiness in life? This life is happy but not long, because our life is limited. Your wife pursues longer-term happiness. Your wife also blessed your family.
Your wife's thrift is a blessing, but she despises material comforts. But respecting incense doesn't need to spend more money than anyone else. Sincerity is more important. The key to learning Buddhism is to cultivate the mind.
Relax for a while, put aside your prejudices for a while, and try to understand Buddhism. Will open another world for you.
I wish you a happy family.
