Is $250 fair enough?

{If you read it till the end. THANK YOU}

So I'm currently staying at my sisters house. Hubby and I . Not for free of course but not much either. Well she agreed our rent would be $500 a month food and all including utilities. That's a cheap price I was thankful. We are paying for a small bedroom thats it. Well I let her know that we would possibly be moving the beginning of October cause we've been hunting for our place. Her response was well if your not out before the 1st, in some apartments, they require a month worth of rent if you're not out on time. So im like ok she's playing with me. You see. We weren't in a position to start looking last month we've stayed here for 8 months but we finally got what we needed to move out on the 1st of this month and we started applying right away and first apartment we applied we got it. Well we got the call today 10/10/2017 about our new apartment and we can move in right away (see the last couple of months have been miserable and both her and her hubby have been hinting we've over stayed our welcome) It's all good I feel the same way they have kids and need all the space they can get I get it. And last week my sister was telling me I shouldn't rush that we should take our time save up more? We have a brother whom is in a tough place right now so I've let him borrow $600. We've been helping financially here with her- i wont lie our savings have been cut by half cause of all these unexpected expenses. So I told her today we got approved and we are leaving I was hoping we could move out on the 24th to give us time to move all of our stuff and do what we need to do. Unfortunately we can't cause she wants full rent if we do stay. I get it, it's almost a whole month of living here by then but I guess I was hoping she would let us save up the money for our next rent. Her hubby and her get paid well and their rent is $890 a month. Mine on the other hand will $1,095 😩 not her problem I know. But because of other things I don't want to mention here we've been miserable. Maybe it's because im not like that and her being my sister I wouldn't do that to her especially if I knew the reason why she had to stay with me. There has been so much said and done to me by her that i guess i feel this as one more blow that has hit me hard in my spirit. And I don't even think its the money that makes me feel bad. It's how she said it and how she is demanding it as if im just another person she just met. I don't know we are 5 siblings and she is the only one who is like this that's why it hurts.

I'm not staying the full

Month so do you think $250 is good enough. I wasn't trying to be like this but I paid a bill she couldn't pay that was in collections yesterday. If i pay her half of what the $250 Would that be rude?

I'm just hurting here seriously my feelings are beyond hurt but like I said there is more to this story.
