<prompt> Human: My gf bought a new car in July. a 2016 Kia Forte and last week she got home from here new job and someone crashed into it as it sat in her driveway. her credit was 680ish when Kia motors finance gave her the auto loan of 20k at 8. Its now like 650. She lost her job, hence the new job, Could I add her to one of my accounts and just keep the card and not use it to kinda build up some credit a little faster?  <response>: Dont get into debt with someone you arent married to. Dont share finances either.
