For my summer internship, I needed to go to a different city which meant I had to find a place to live. I was browsing any rooms to rent near the area when I saw a $500 per  month post which I was interested and contacted the person. I was shown the place and everything looked fine. We reached an agreement and rented me his extra room for $500 a month, everything included, for 3 months. From mid May to mid September (this is important)

However, right away I realized I hated the place the first day. I live in Texas, which is pretty hot. I was never told that the A/C was to be turned off when we were both out of the apartment, so when we arrive from work the inside was a crisp 85-90 degrees. It was the summer. The A/C took all night to get to a temperature of 75-80 degrees. Sweated every night btw. No big deal, I didn't care. Just put up with it. 

However, around the second month, I was asked if I can help with electric bill because it was summer and light bill is higher, I was like, "why not?" So I said I'll help out. Big mistake. From then on I was requested money to help for light bill. Again, I said why not. Usually $100. No big deal. 

My last week staying there came up, I thought that's it. Nope, more money was  wanted, $150 for those two weeks for the light bill, when I confronted the person, saying that I couldn't even leave the A/C on, suffered every night with sweat, plus, I would leave on weekends to stay with my family, and that I didn't even have a TV in my room so I couldn't have used that much  electricity and that my kindness was being taken advantage of they replied, "$150, no further discussion". 

I was mad. So I told the person I was paying them my next check because I was broke (college student) and gave the person $70 (all I had). Decided to not pay him after I left. I feel bad, that's not necessarily like me. AITA????
