Okay confuse much is Brittnay and Santana Gay or what are they in love or what huh?

Brad Falchuk said that Santana is "definately a lesbian". Brittany is most likely bisexual.
And yes, they both love eachother, but Brittany also loves Artie.

Basically what the other poster said. Although Brad said Santana is lesbian, she actually strikes me more as pansexual, which just means she doesn't give a crap what gender they are, she'll be with them and is open to any type of relationship.

Brittany is probably bisexual, because it really does seem like she cares for Artie and Santana. Santana told Brittany she loves her, and while Brittany does love Santana, she also loves Artie and doesn't want to hurt him by leaving him all of a sudden for Santana, which breaks Santana's heart and now Santana isn't really talking to Brittany and being kinda mean to Sam.

I Honestly Believe that Brittnay and Santana are Bisexual and They love each other but Brittnay is with Artie
