<human>: Can you summarize the given text in a few sentences?

Three bedroom house:

Three people: myself [F31], the kid 2.5[f], the boyfriend[M39]. We've been dating over a year. 

The kid and I moved into my boyfriend's place. Rent is $1648. The kid and I share one bedroom (the master) and pay $800 a month. My boyfriend pays the remaining $848 and occupies the other two bedrooms. He also pays the utilities.

My boyfriend never cleans. He doesn't buy groceries. I do both of those things and cook him breakfast every morning and sometimes dinner.

The child is moving out really soon. When she does, would it be fair to ask my boyfriend to start paying 2/3 of the rent? I will only occupy 1/3 which will be my bedroom. I will still continue to purchase groceries and cook for his ass as usual. Am I being unfair to ask such a thing? Since he doesn't pay for shit in the house.
<bot>: My boyfriend doesn't help out around the 3bd house, we have separate bedrooms. Should I get reduced rent since he has two rooms and never buys food or clean?
