Betrayed

So we have been living in this house that we are renting from my cousins. By all normal standards this house is not livable. The oven doesn't work, the electricity in a few of the rooms doesn't work at all, there are open wires hanging out of walls, the downstairs bathroom doesn't work at all, and to top it all off there is a huge hole in the porch. My husband was very worried about moving in with the electricity the way it is. We have been living like this for a long time and we haven't voiced our issues until recently, well now my cousin's husband is acting like we are ripping them off because we want them to pay for some of the major fixes, such as the electricity that we were promised would be fixed before we moved in. We pay $600 a month, and now he's saying that it sounds like we don't like the house and we should just move because there are "three other families willing to pay $800 a month" So now I'm thinking why the fuck did we move here in the first place! They were desperate to move and have someone move in, and we helped them out, and now as soon as the shit is started to hit the fan and they are having to be responsible for their house now we are a burden and we should just move, so it doesn't matter that for the first month we had to shower at my parents house, and for the last three months I've been making everything in the microwave and on the stove top. Its just so frustrating that we have had to live like this this whole time and we have put our own money into making this house livable and now they want us to move because we are tired of putting our own money into a house that isn't ours.
