Roommates Forgetfulness Causes Rift: AITA for Refusing to Cover Shared Bills?

A 28-year-old man thought he was doing the roommate thing the responsible way, splitting rent, utilities, internet, and even groceries like clockwork. Then his 26-year-old roommate started “forgetting” her share, and the little slips turned into a growing stack of late bills and stress he never asked for.

At first it was the internet, then the electricity, and each time he had to scramble to cover her part so nothing got shut off. He runs his finances like a checklist, while she needs reminders, gets defensive when he brings it up, and acts like money panic is just him being “too uptight.”

Now he’s refusing to cover again, and the cold shoulder says this is about to get messy.

So I'm (28M) living with my roommate (26F), who I've known for a few years. We decided to split the bills evenly - rent, utilities, internet, groceries, you name it.

Everything was going well until my roommate started forgetting to pay her share on time. First, it was the internet bill, then the electricity, and it kept piling up.

For background, I work a full-time job and manage my finances meticulously. I always transfer my part of the money on time to avoid any late fees or issues.

On the other hand, my roommate is a bit more forgetful and often needs reminders from me to pay up. This has happened multiple times, and I'm frankly tired of the added stress.

Recently, the utilities bill came, and she conveniently 'forgot' to transfer her share before the due date. I covered her part to avoid any disruptions but decided to address the issue this time.

I calmly brought up the pattern of forgetfulness and how it's affecting me financially and mentally. I suggested setting up automatic payments or finding a solution to ensure things are paid on time.

Instead of understanding my perspective, she got defensive and claimed she's busy and it's not a big deal. She accused me of being too uptight about money and making a fuss over nothing.

This reaction really irked me, as it felt dismissive of my concerns and responsibilities. Fed up with her attitude, I made the decision to stop covering for her.

I told her I won't pay her share of the bills anymore if she can't uphold her end of the agreement. She was visibly upset but didn't say much.

Now, tension is brewing between us, with her giving me the cold shoulder. So AITA?

I feel like I'm being taken advantage of and shouldn't have to bear the consequences of her forgetfulness. But at the same time, I don't want to strain our living situation and create a hostile environment.
