<prompt> Human: So few months ago I go out of my parents phone like and got my own line. My sister heard I was joining Verizon and said if I would let her switch to Verizon with me and she would cancel her line with t-mobile since she said tmobile coverage sucked for her around her work area while her co-workers with verizon had better coverage. So I said sure as long as you give me your half on time. Man I regret that.So my sister works a full-time job and only gives my parents 300 for rent every month while she makes around 1500-2000 each month. I dont know the exact amount but I know she gets paid around 400 every week then she also helps one of her friends get drivers for his company and she gets a weekly commission from him based on how much money the drivers make on the week.But somehow despite making all this money and not really having any responsibilities SHE CANT NEVER GIVE ME THE DAMN F phone money on time. She has made my account go overdraft 2 times or left me with no money multiple times too. Not only that but she makes international calls frequently so thats extra charges and also changes her phone number often because she thinks that will solve spam calling her number. Then expect me to just pay for half these charges for her.So what you guys think? Would it just be better for me to pay my phone bill alone despite the fact that MAYBE one day I wont have the money I do have a small emergencysaving fund which I could use regardless but I avoid using it as much as I can to pay it on time that month but she will?I guess this in a way is a lesson for me to not share bills with people unless you know FOR SURE they are responsible with their money.EDIT: Forgot to also say that Im unsure wether to do it or not because I took a brand new phone when I switched to Verizon because I gave the old one to my stepdad and my current phone is only 25 paid off and I dont have the money on my checking account to pay it off but I could pay it off with my Amex card that has a 800 balance on it and no interest until September next year.  <response>: Your best bet is likely just to tell her that you cant pay for her line and that youre going to cancel it today if you dont have the money today. If she doesnt come up with it today, shut it off. It sounds like youve given her multiple chances to pay and she hasnt. Dont feel bad about her losing her . Its her responsibility. You can only be responsible for yourself. Consider it a lesson learned for both of you.
