I had an argument with my boyfriend and I feel bad about it? AITA?

Am I the asshole for saying the following:

Had a semi argument with my boyfriend about being a stay at home girlfriend. I told him that it was something that will probably never happen because he can't afford it and probably never will be able to. (I know that was pretty harsh but the truth).

He said then why are you with me if you want to be a stay at home girlfriend and you think I will never be able to provide you that.

I said I'm with you because I love you and want you. The lifestyle is a want but not a need I told him. I can do without the lifestyle as long as I have him. But I'm not going to lie to say that I envy those girls that have that lifestyle.

Would I get with a guy that could provide with that lifestyle? No because I love my boyfriend but again I wish I could be a stay at home girlfriend.
