Internet rallies around person wondering if they're wrong to make fiancé pay majority of bills

We live in a world that requires people to constantly toil to afford even the basic necessities in life. In such conditions, people cannot be too liberal with their financial spending, especially when it is for another person. This is a major concern among many couples who are about to start a new life together. One of the instances was shared by u/Majestic_Stuff3229 on Reddit as to how drastically their expenditure skyrocketed when their fiancé and his two kids moved into their house. Laying out the specifics, the individual pointed out how splitting expenses in half was totally unfair to them.

Being a single parent of 2 boys aged 11 and 10, the individual happily welcomes their fiancé and his two daughters aged 12 and 13. After 2 months of noticing an evident increase in their expenses, the user, who is a financial consultant by profession, decided to break down the costs to give the Reddit community clarity. Speaking of their monthly expenses before their fiancé and his kids moved in, they wrote, "Rent: $1800, food for me and my two kids: $460-$520 a month (depending on whether or not I bought in bulk), electricity: $127, water: $86, heat/hot water (run off the same tank, due to me having heated floors): $190-$210 a month."

They also had other spending like personal subscriptions and insurance which they didn't want to add to the issue in question. But, the total expenditure after the fiancé, his kids and his two dogs moved in seemed to have almost tripled. "Rent: $2300 a month (they brought 2 dogs, so now there are fees), food: $1600-$1720, electric: $392, water: 271 and heat/hot water: $438," they pointed out. The engaged couple discussed before the move-in that they would compare the bills from before the fiancé moved in and he would be responsible for paying the extra. "However, when we did that, he became irate and said that if we did that he would be spending more than I am or ever was even prior to him moving in," they explained.

Despite him and his kids contributing significantly to the expenses, the fiancé found it unreasonable to pay his fair share and rather wanted a 50/50 split. "I told him this is what we agreed on. My bills went up drastically when they moved in and I won't go 50/50 and pay more than I was prior to them moving in," the individual added. But this argument turned bitter and the fiancé started having second thoughts on the whole arrangement. "I told him until he makes a decision on whether he's staying or leaving, he will be covering what he agreed to," they said in the end. The individual however was skeptical if they were wrong to expect the fiancé to pay the majority of the bills but the internet rallied around in their support.

"There's more to this than just numbers. There's additional cleaning, less personal space and more commotion. Not to mention increased wear and tear on furnishings, linens and other shared-use stuff. Your plan sounds fair to me so," said u/calacmack. "NTA. Your food bill had tripled. That's obscene. Either he and his girls have always lived like this or now they're just taking advantage. This is a hill to die on," remarked u/Quiet_Hamster6509. "Let him move back out. Those are crazy increases and it's not fair for him to expect you to pay a lot more to cover the costs he's increasing," added u/Amazing_Reality2980.
