OP's brother are moving into the house
This is not fair to the OP
OP has offered the following explanation for why they think they might be the AH:
I feel like I may be the AH because I am putting my mom in a tough spot either way. If I move out she will be in a financial hole. If I stay, then she will have to make her sons that don’t get along share a room.
Both of them should share
The OP is paying rent
OP's not spoiled
OP added this edit later on
Bob is just moving back temporarily and trying to save up for a house. he will be paying rent. chad is still going to be paying half the rent for his ex and I think that is the right thing to do. as for child support going to me, i don’t have a relationship with my dad and I haven’t talked to him in about two years.
According to my research he is not obligated to pay it once I move out. I only pay my mom $450 a month and that also covers my phone bill but I give her random amounts throughout the month if needed on top of that.
OP's brother can pay her
What a stupid law
OP's dad pays child support
It sounds volatile
The OP added another edit
Many Redditors say that OP's mom is favoring her sons and abusing her youngest child. Some even asked if they were under any pressure to behave and pay rent while residing in the house.
If at all possible, OP was advised to move into the dorms as she shouldn't be paying rent on top of her child support, which is meant to fund OP's living expenses. The OP was declared not the AH, and that's a wrap.
