Apartment price splitting dilemma

<p>

</p>

<p>Is he responsible for causing this complication or is it the guy who wants to reside at the living room?</p>

<p>

</p>

<p>How about you switch the roommates and put one of them in the single?</p>

<p>Overall, I would like to know who is responsible for this mess when it was supposed to be an equal split for 4 of you.</p>
