Am I selfish for buying a treat once a week with my money (working 2 jobs, he works 1 that ranges from 20-40 hrs depending on the week)

He says because sometimes I say things like, "oh hey I can get a book" instead of asking if he wants something I am selfish.

Most of the time we spend it on treats for both or go to a movie but once in a while I'll get something that is just for me (once or twice a month)
