<prompt> Human: My boyfriend about a year ago took his dog to the vet. I agreed to co-own a credit account with him so he could get approved. Since then he keeps missing payments. I have to remind him every month. He also lied about paying it once and it was late by over 30 days. My credit score has dropped around 100 points so far from this. Is there any way I can stop this from affecting my credit score? Or is there maybe some sort of damage control on it I can do? Any advice is appreciated.  <response>: Only way to get your name off of it is likely to pay it off completely and then close the account. Unfortunately when you cosign with someone this is what happens. Its like being in a boat together, and if one of you starts shooting giant holes in the bottom of the boat, you both sink together.
