<prompt> Human: My fiance and I are ready to tie the knot but Im worried that us getting married will affect my credit, I have extremely good credit and hers is garbage. If it does how bad will it knock me and for how long?  <response>: No, it wont be affected. Money is the 1 reason for divorce however. What led her to have horrible credit? Is she financially irresponsible? Let me tell you, if you have your act together and she doesnt, this will become a huge issue in your marriage.
