Glee Kurt & Blaine

Kurt: Oh, excuse me! Um, hi, can I ask you a question? I'm new here.Blaine: My name's Blaine.(They shake hands)Kurt: Kurt. (smiles)

Kurt is a young somewhat confused teenage boy who feels he maybe different to other guys his age but at one time tries to conform to what society deems as 'normal'. He joins the football team and becomes the kicker and proves to be great at it as long as he does Beyonce's Single Ladies Routine first to warm up.
David constantly ridicules him for this and the other guys on the team are not happy about it either but they soon come to terms with doing the routine too as it seems to relax all of them and they end up playing better.

Brittany: "You're pretty much the only guy in this school I haven't made out with because I thought you were 'capital G' gay. But now that I know you're not, having a perfect record would mean a lot to me. So, let me know if you wanna tap this."

Kurt goes one step further and changes his usually flamboyant and sometimes garish fashion sense to that of a casual teenage guys and begins to date Brittany. The two don't really seem to have much chemistry as Kurt is gay and seems to only ask Brittany questions about males whilst Brittany does not seem to put out as she is secretly sleeping with Santana. Brittany's main reason for wanting to date Kurt was that she had kissed everyone else in the school except him. No one seems to believe their facade of a relationship if anything people are more confused than accepting.
Kurt and Blaine's relationship was not a love at first sight sort of romance nor was it an mutual attraction between the pair of them in the beginning. Kurt always seem to fancy Blaine from day one but since Blaine already had a crush on someone else he was not interested. The two first became friends when Kurt transferred to Dalton Academy from McKinley High as he was constantly being bullied by David Karofsky due to his sexual preference. It soon comes to light that David only bullied Kurt as he was out and proud and David was too afraid to come out.  Kurt and Blaine seem

like the perfect couple and when Kurt returns to McKinley High Blaine soon follows as he can't bare to be apart from him. The two seem to be going strong but when Kurt graduates from High School and moves to New York for college tensions start as the distance and the loneliness takes a toll on both guys however only Blaine acts upon it and cheats on Kurt resulting in the two breaking up for a period. They reunite and Blaine proposes which everyone seems to be ecstatic about, but the stresses of an engagement separates them again this time with each of them dating new people. 

Blaine: "We met right here. I took this man's hand and we ran down that hallway. And for those that know me, I'm not in the habit of taking people's hands I've never met before but I think that my soul knew something that my body and my mind didn't know yet. It knew that our hands were meant to hold each other's, fearlessly and forever, which is why it's never really felt like I've been getting to know you, it's always felt like I was remembering you from something. As if in every lifetime you and I have lived, we've chosen to come back and find each other and fall in love all over again, over and over for all eternity. And I just feel so lucky that I found you so soon in this lifetime because all I want to do, all I've ever wanted to do is spend my life loving you. So, Kurt Hummel, my amazing friend, my one true love, will you marry me?"

Surprisingly Blaine ends up with David and Kurt someone he meets online. 

However just like Santana and Brittany, Blaine and Kurt belong together. With the manipulation of Sue Sylvester and the agreement of Brittany and Santana (well mainly as she can not say no to Brittany.) Kurt and Blaine get married along with Brittany and Santana. As they have each found their soul mates the one person they will always love and want to be with no matter what.
