I'm not going to cover rent when my housemate's so refused to pay their share
Do you know why they don't want to pay their share?
Yes, I know why they don't want to pay.
Even though it can be frustrating to have others not pay, it is not good to not pay your bills. You should go to the landlord and have him settle the issue.
Heck no, I'm just not paying anymore. If the rent goes up I won't be able to afford it anymore anyways. I might get kicked out and then have to go to a shelter. But it is better than paying right now.
Rent is something we all have to consider. Don't worry about rent going up or your housemate's share of the rent. Just pay your own.
