Around November 20th, my sister couldn't make her rent and was being kicked out. She came to my mothers complaining she was getting kicked out and that she was just going to live on the streets with her kids. My mother is a very kind person and would do anything for her kids even if it hurt her in the end. So she offered my sister a place to stay. My sister accepted and even said she would help pay for the bills and fill the house with food while she was staying there. I was there at the time all this was going on. There was no written agreement, it was just a verbal agreement. So come the start of December, my sister helped pay for half the rent. I thought this was great for my mother because it would not only help my sister get back on her feet, but it would also help my mom to save some money. We are not a rich family and we live paycheck to paycheck.
It wasn't until recent that my sister started to be, well, a bitch. She's all a sudden claiming she never said she would pay for some of the bills and help with food. I assumed food wouldn't be an issue because she gets 400 dollars in food stamps every month. She'll get this massive attitude if anyone touches her food, but she eats my moms food no problem. When my mom asked her if she could help pay for at least the cable or electric, she'll get an attitude and claim she doesn't use the cable or electric. Yet her kids watch T.V all the time, they leave the T.V on all night. So not only do they use the cable, they also use the electric. It's gotten to a point where my mom doesn't even want to be in her own home when my sister is around. I've told my mom I was going to say something, but my mom begged me not to say anything because it would only make things worse for her. I'm not sure what I can do. My sister is treating my mom like total crap and my mom does everything she can to help her out. It just really hurts me to see my family treating each other like this. I told my mom that if she isn't going to help with bills like she said she was and if it isn't working out, then kick her out. Knowing my mom, she won't do that because she doesn't want to see the kids on the streets. And knowing my sister, she wouldn't let the kids stay there.
So I'm just looking for some advice on what I can do or what my mom can do.
