<human>: Give me the gist of the text in a nutshell

As the titles suggest, my fiance and I are in a tight spot with bills and money in general. We both work for an amazing company, I'm full time and she's part time. She also goes to school, and takes care of the our two kids when I'm at work on the weekend and when the daycare is closed. We own our house and mortgage isn't that much a month. But we are struggling right now, we are on [WIC] ( but it still doesn't help with everything. We've both agreed that in between school and the kids, that she's going to start picking up 36-38 hours a week,(that's the max our company will let part timers get each week) to help out with bills.

To get to the point, each year around tax season she let's her mother claim her on her taxes, and I claim independent and our 2 kids. I make more and work more hours than she does, so it's only smart for me to claim both of the kids, house, and other things during tax season. But we can clear up every single one of our bills, and still have some money to plan for future bills, or pay up on bills so we can start saving money in the future. I brought it up to her in the car on our lunch and she basically stated that she only finds it fair that her mother get to claim her since her mother took care of her and raised her. I told her that I understand that she wants to help take care of her mother,(who is also like a mother to me), but that we need to focus on our own family right now. I told her that sure, the amount you will get back being a dependent will help, but when I was working my other job,(where I made significantly less, and I started claiming independent, the amount received was much higher. At that point she through it in my face, that it doesn't matter cause my family wasn't hurting for money as much as hers. There are other things that also go into this story, but her family members are redditors and I'm not going to  bring stuff up that its irrelevant to mine and her immediate family.
<bot>: fiance wants to keep letting her mother claim her on her taxes so her mother gets some extra money, when we could use it to support our own family and pay bills instead.
