they have normal fights, they're normal people, they have the most normal relationship...

or Mike/Tina.

I would say Artie/Brittany but they aren't really the definition of sane :)

Carol and Burt?

@Surpr1zzm33 we don't see enough of them to know.

I think they are.

yes they are sane
but they are boring e.e

and Finn/Rachel as well

and Sam/Quinn are anything but healthy

@Costa: Exactly, that is why I named them... xD

But I really don't like them together :)

Doesn't everyone notice how they stay in the background, and hug each other, and Tina loves Mike's abs, and Mike loves Tina, and even though Tina briefly questioned their relationship they stayed strong, and they met at Asian camp, which is pretty adorable. And they're Mike and Tina. They just don't have problems!

^LOL totally agree.

Whoever picks Finn/Quinn is crazy !!!!!!!!!!!!!!

Definitely Mike&Tina. At least, they try to make their relationship work. And it's not only, as people may say, due to physical attraction, it's more than that, it wouldn't have lasted that much longer if it was.

By miles.

I don't know why Sam/Quinn are second but, other than Mike/Tina, Kurt and Blaine have a pretty good relationship. I can picture Mike and Tina marrying each other someday. But stuff can happen.

At first I thought Mike/Tina.But then that song that Tina sang to Mike on Valentine's day popped into my head.... It was a little insane and unhealthy how in love they are.... Finn and Rachel do fight a lot but that's what makes them stronger and they've never gone like COMPLETELY crazy for each other...
