I find the things my husband does really cute and I like to creep on him.
That's interesting. I wonder if you can tell me about something in your life that you feel is weird and do not understand why.
Sometimes I spend money on things I don't need.
While watching your husband do cute things is fine, you should avoid spending money on things that you do not need. Spending money frivolously is wrong because it's a drain on your budget and can impact long term financial security. If you have a compulsive need to shop you should try finding other hobbies to do that are not as expensive.
But he is really good to me, he deserves me to take care of him and I want to get him things.
But you would be able to take care of him better if you didn't spend your money on frivolous things for him. You could be saving for both your futures.
