should i care if my gf mom cut me off?

my gf mom cut me off and she's no longer going to talk to me. she got upset bc i let her borrow money twice($50) and i'm 16 years old. i got upset because i felt like she was using me. i would go over and spend half of my paycheck on her, my gf, and sometimes her brother. and i texted her saying hey can you send me the money and she got really upset and she said she's not cool w me anymore. this is prolly confusing asf. basically, she got mad because i texted her multiple times after she said she'd give me it but i only was trying to help her with giving her different ways to send it. maybe i was wrong but she completely lashed out and said it was a big "fuck u" to her for me doing that. and she got upset that i involved my mom which i didn't. i only told her about it and asked for tips and that's it. AM I WRONG?
