Rental Application, 1 bad 1 good?

Okay, this is a rephrased version of a previous question I had somewhat. Basically I've been denied renting due to poor history and credit and I know if I apply for a place I will get denied. Knowing now that both my boyfriend and I will have to fill out applications for rental, He has very good history and credit. If I'm denied and I hear the same thing again about why, will that ruin our chances of a place? Or will it be okay since his rental stuff is okay and in check? So 1 good application and 1 bad, does that disqualify a couple for renting?
