<human>: Can you condense the text into three sentences or less?

G'day Reddit, thought i'd post a conundrum I've just had and hopefully get a few different perspectives on the situation.

Ok, just over a year ago i was still living at home. My closest mate needed to travel back to Brisbane to complete his degree in Nursing and as he had no friends or family here he could stay with and figuring it's high time i moved out (22 years old) we started looking for a place.

I initially helped look for a place but stopped, partially due to working long hours that often required finishing late and starting early and partially due to laziness. At the time, my housemate was on a uni break but not working so had a bit of free time.

Fast forward to now, we moved into our second rental property (2 bedrooms, kitchen, lounge, small dining room, sleep-out). We wanted a 3 bedrooms to have more people in it. My housemate found this place as we had no 3rd person interested in moving in at the time.

Last week, i was called away down to Victoria for the funeral of my grandfather but was advised last Wednesday that my housemate had told his brother he could move in, under the plan that the living room would now have doors installed and become a bedroom, my housemates room would become the living room, and the brother would take the sleep out. I was pissed off first that i hadn't had this mentioned prior and my housemate went and did it.

I got back home last night to find the house in a state of semi halfway house as another friend (met a few times before) was now moving in. I was told the new plan by my housemate in front of both the new additions and found myself forced to agree (i didn't feel right telling them to just fuck off)

The two new guys leave to head out and i bring it up with my housemate, saying i was unimpressed with the way it was handled. Huge fight breaks out, housemate said that as he had found the houses with little to no help from me that he would do what he liked.
<bot>: Housemate has invited two more to the 2.5 bedroom house without talking to me and says he'll do as he likes because he found the house.
