Excellent Idea … :k:
other than that, I am sorry to say PCG but you are stuck. Only 3000$ can bail you out. Any other action will only make your everyday life difficult.
If you are doing what you said you are doing then you are pretty generous. When I was with a roommate, I had the master bed (with bath) and I was paying 55% of the rent (and he was paying 45%). If I used to cook, he used to clean and wash (and vice versa). We both came to US together and I bought car before him so I drove him to places for 5/6 months (even to his Moharram Majlis although I am not a Shia Muslim .. 40 miles every night ..10 nights ) …but then, we were very good friends unlike your situation
