Resistance to buying flowers for myself

This is simple but recent example of what goes through my head whenever I’m faced with the desire to buy myself something nice – despite being comfortable financially. How can I overcome this and treat myself better with out indulging and overspending. Many thanks.

C: I discovered that there is a pop-up flower stand down the street from my house.
T: I love flowers. I feel loved when others buy me flowers. I should buy myself some. On second thought, I don’t need to spend the money. I don’t really need flowers.
F: Dejected
A: I do not buy myself flowers.
R: I don’t enjoy my home environment as much as I’d like to.
