I am in my early/mid twenties. I go to school and have a job on the side. 
I am an only child living in an appartment that my parents bought for me (not that uncommon where I am from).
My parents like to buy me nice things and give me me money every month. Not gonna lie, I enjoy this and I am very grateful for my situation.
I have told them that I don't love them because they buy me stuff, and that they don't need to do so. They respond buy telling me that I am their only child and they want to spend money on me.

I don't think my parents feel coerced into spoiling me and I could definitely make it on my own without their financial support (albeit with a little adjustment to my spending). But I still feel bad sometimes about their money when I am an adult. AITA?
