Brittana

"Santana — I've been bullied, outed and misunderstood. Brittany — The world seemed so scary and confusing. It was just too fast, it made me feel dumb just because my brain worked differently. Santana — I would have said a thousand times yes. Brittany — I would've suffered it all, just for the tiny chance to be standing up here marrying you. Santana — I'm a work in progress. Brittany — I'm a work in progress."

Canon
Brittany and Santana had a 'best-friends with benefits' arrangement. This was hinted at in various instances in Season 1, but it was made official in Season 2, when the two were seen making out (Duets). Santana is often tough in her relationships with other people, she shows the softer side to her personality when she is with Brittany. The two are often seen intimately cuddling, holding hands and walking with their pinkies locked. The pinkies locked thing seems to be their handshake (even prior to them dating). Also, they are often seen wearing matching bracelets and backpacks.

In "Duets", they are making out in Brittany's bed, and when Brittany says she would like to sing a duet with Santana in glee club, Santana is very rude with Brittany, saying that she is only making out with her because Puck is in juvie. Brittany then starts dating Artie to make Santana jealous, which works. Santana is jealous and makes Artie break up with Brittany. Although they end up dating a few episodes later. In "Sexy", Brittany finally confronts Santana about their relationship. They end up confessing their love to one another, but don't end up dating because Brittany stated that it would be wrong to break up with Artie because she loves him too. Also, Santana is too afraid to be an out lesbian because of her reputation. Brittany eventually breaks up with Artie, in "Rumours", when Artie begins to suspect of her relationship with Santana and calls her stupid. When they began dating, they kept it as a secret due to Santana's fear of what others would think. In season 3, they officially called it a relationship in the episode "Pot o' Gold", when Santana hesitantly inquired if they were dating over dinner at Breadstix. Brittany responded with statements implying she was under the assumption they had been dating for a while. In "Mash Off"/"I Kissed a Girl", Santana is outed, forcing her to be honest about her relationship with Brittany. In "Heart" they kiss for the first time on screen. In "Saturday Night Glee-ver" Brittany tries to help Santana to realize her dream, which is to be famous and gives her an acceptance letter to the University of Louisville.

In Season 4, Santana goes to college, while Brittany is forced to repeat her senior year, but they continue dating, for long-distance relationship. This, ultimately, wasn't good for the girls, in "Britney 2.0" Brittany is seen sad, and missing her girlfriend. In "The Break-Up", Santana tells Brittany she doesn't want the pressures of a long distance relationship; causing them to go on a 'break'. Santana assures Brittany that it's not a break-up, although Brittany says it feels like one. In "Glease" Santana back to McKinley to play Rizzo in the musical Grease. They talk and confess that they feel really miss each other, however they remain separate. In "Diva", after discovering through Tina about Sam and Brittany, Santana back to McKinley to win Brittany back, but at the end of the episode, Brittany says it will not break up with Sam and pushes Santana to follow her dreams and move to New York. In "All Or Nothing", Brittany reveals that was admitted by MIT in Boston. She says an emotional goodbye to Santana and her friends.

In Season 5, Brittany returns to McKinley completely depressed, for MIT has changed her (100). Santana sees this, and helps her by forcing her to sing "Valerie" with her. Brittany kisses Santana at the end of the episode and Santana states that it wasn't a good idea, because she worked so hard to get over Brittany. In "New Directions", Brittany suggests they run away together. Santana declines the offer, but agrees to go on a vacation with her. Santana also tells Brittany to move in with her in NYC.

In Season 6, "Jagged Little Tapestry", Santana asks Brittany to marry her and she agrees.

In "What the World Needs Now", Brittany and Santana plan their wedding, hiring Artie as their wedding recruiter, later in this episode Brittany attempts to reconcile the relationship between Santana and her Abuela, resulting in Santana singing "Alfie". After the song, Brittany and Santana try to get Abuela to give up her hatred in homosexuals and come to the wedding, she declines. At the end of the episode, The New Directions, The alumni and Will Schuester gather in the auditorium to sing "What the World Needs Now" to Brittany and Santana. During the number they are seen at Mr.Schuester's apartment together with the others.

In "A Wedding", Brittany experiences a nervous breakdown about the wedding, especially when Santana sees her in her bridal dress. They eventually resolve the issue, and get married.
