<human>: I don't know if I am being unfair to my bf but here is the deal:

My toilet overflowed and half my room got flooded. I'd say there is about 30 articles of clothing, 2 coats, 5 pairs of shoes soaked, rug ruined. Maintenance was able to suck out the water and give me a humidifier but my room reeks of a chemical smell that makes me hard to sleep and I now need to sanitize the floor because of the toilet water.

My bf's sister flew into the city last week and was staying with her girlfriends. She's going to stay at his apartment for the next 3 days. They're meeting up tonight and I asked if it would be ok if he spends about 2 hours with me to help me clean up so i dont spend all night doing this. 4 hands better than one! He says he wants to help but he promised his sister that they would meet after work and would feel bad if he had to leave her alone for 2 hours, and says he cannot spend time to help me out and won't offer an alternative solution

I'm ok if this was an isolated solution but we had problems in the past where he won't help me when I had to move. I broke up with him, but he promised he changed regarding that..

Could you distill the essence of the text into 1-3 sentences?
<bot>: bf won't help me clean for a bit because he needs to be with his sister? Am I wrong to expect some help from him?
