They're Out Your Life- Now Start Over
When it comes to credit, it takes everything you have to start all over. Especially when you had a joint account with someone who you thought was responsible and was gonna be your forever.
First thing is check your credit report. Dispute accounts that don't belong to you. Dispute accounts that have been assigned to a different collection agency. Make any payments on any accounts that could be paid off quickly with an agreed amount with the creditor. Start establishing new credit in the meantime.
