Is it a red flag if my boyfriend insists his future wife must work?

So I am dating this guy it's been 2.5 years now... everything was going well, he is studying and so am I , we are in late 20's now.. so lately he's been acting distant with me for the reason that it will take him long to settle down and get a job... So he told me that in future don't expect much from me if you yourself are not working... I want my wife to be working etc and my mother won't like if I marry a girl who is not earning... i had always wanted to work that's not the issue but I had once mentioned maybe I won't work after kids etc... so now he told me it's not gonna work if you can't support or work as he is the only child nd has to manage things and parents'responsibility as well.. so if you are not earning you will just add to it etc...

Now the thing is I do want to work , but love has taken a back seat ad I don't know if I should marry this guy or not? is this red flag?
