Feeling like a failure

Husband commented that i watched 2 movies this month, suggesting disapproval of my spending. I felt ok with it but it started to bother me today....

How can I have a life as a stay at home mum if I don't spend money to do things that's enjoyable?!

I am already sacrificing 3 years of career life, and of cos undeniably it's a good exchange because now I have a baby life and it's most fulfilling to spend time with my child. However, it is also tiring, isolating, without help, and restrictive because there's only so little things I can do while looking after a baby!

I feel myself getting angry at such comments.
