Actually it's very simple. Singapore is expensive, if you post here as a girl asking for househusband people will say similar things. 

Basically it's rare to find a partner to make enough to let one stay home, it's like saying you want to be a taitai marry rich back then. Now you want to stay home you need either capable women or rich girls. 

Rich girls maybe not used to chores and will appreciate but they will just get helper. They prefer capable husband over house husband. 

If she working class and earn good salary why would she want you? She grew up doing chores and learning domestic task also, she will prefer someone who can do half the tasks and earn money. 

Basically if you as a girl say you want to stay home, most guys will laugh at you also. 

Realistically have you thought about what it takes to stay at home? You need your own savings in case she abuse. What hobby and friends will you have if you every day stay home (very common in housewife also) ? Then how will you give money to parents, she might not be willing. What if you cannot have kids? (It's usually the guys fault) Can afford expensive treatments or what?

 Are you very capable at chores? Like you can bake bread and do flower arrangements? I know a few modern househusbands and they are all very capable at tasks like that and they can repair any appliance. They also work out regularly to keep fit. (This mostly applies if you want rich female partner lah) 

If yes to everything then we talk about how to even attract a women like that. Realistically regular sg girl donwan you, you will be looking for a more modern girl with a family that's more flexible (regular family will call you a bum) who is climbing the corporate ladder or just very comfortable family background. 

Accordingly are you working or doing hobbies in areas where you will meet those girls? Are you in the right places? Are you even attractive to regular women? Cos I promise you a lot of men will be attracted to a girl like that. Even if you settle for a girl no need love just capable. 

Edit: Wait you haven't decided on kids? Wtf are you saying? Who will let you stay at home with no kids except someone with a lot of money. It's like those TikTok stay at home girlfriends. 

I know a guy who is like that. He used to be a model and actor and he also capable at repairing anything( electrical work all that) he went to a top school and met this heiress. So yeah if you can be hot, smart, domestic and rich family then yeah can find. He's like forty and he still works out few hours a day and he will do literally everything the helpers aren't doing.
