Ludacris' GF Eudoxie -- I'm Still Gonna Marry My Fertile Partner


' longtime GF Eudoxie is turning a blind eye to her BF's infidelities that produced a kid ... because she's still determined to marry him.

Sources close to the couple tell TMZ, Eudoxie forgives Luda for impregnating baby mama Tamika Fuller.  Luda claims they were on a break when he hooked up with Tamika.  Sound familiar, Dwyane? 

We're told Eudoxie -- who's been dating Luda since 2009 -- is emotionally hurt, but she too is taking the position they weren't a couple at the time of conception ... even though their Instagram suggests otherwise.

As for Ludacris' impending child support battle with Tamika, we're told Eudoxie will make sure the rapper supports the kid like a responsible father.
