I want to get married but it feels unrealistic

Getting married early

So, recently I've been thinking about getting married but then I was like it's going to be a hassle and especially since I'm like only 18(will turn in 2 months). But now I feel like i need to get married already, the thing is my mom isn't really well off, I used to live w my aunt and uncle and it's been a month almost since I came here to live w my mom.

So I did tell my mother today that I want to get married and she agreed. While we were discussing that she said I'll have to learn "skills" so that I can survive whereever I'm going. And she also mentioned I gotta do all the house chores and stuff, and then also birth kids. And I'd have to leave my studies and everything also.

But the thing is,

what I want is to get married to someone who is already financially stable, and will support me through my studies and stuff. And does not want kids, because that's js a huge no for me.

And else I can do,whatever he says. (Within reason)

I can cook for him and stuff if he wants me to.

So I'm doing CA inter, and I want to continue my studies while being married and I want my husband to support me through that, because ik damn well that after this I will be earning good money. So this way I can return whatever he spends on me too.

But I feel like this might be unrealistic,no one would be willing to do that,and even if someone does agree to that,he might change his mind, and Id be in more trouble. Cuz there would clearly be a power imbalance and u never know when someone changes their mind.

So,do u guys think there's someone out there who would be willing to do it? Or is my mom right?
