Yeep. :P

With Glee mostly. I used to love Finchel and Quick, now I don't ship them at all. I didn't like Will&Terri and now I like them, I loved Will&Emma and now I just like them. I never really thought about Santana&Puck and now I love them, the same with Quinn&Arite, Brittany&Arite and Brittany&Santana.

Naley is the only couple I can think of at the moment, that I loved and after season 5, I don't care about them, at all.

Well. Never if I strongly hate or love couple. I never leave loved couples and never start to even like hated couples ;p.

But I can stop caring about couple I just liked or start loving couple I only liked before or didn't care about ;p

Sometimes I'll ship a couple, but then I'll ship one of them with someone else more. For example, I used to ship Ted and Robin from HIMYM, but now I love her with Barney. In Glee, I'm thinking that Will should just be on his own for a while, slow things down a bit.

Yeah; I used to like Stelena, now I hate them; used to like Serenate now I hate them; used to like Delena now I love them; used to hate Dair and Nair now I like them; used to love Chair now I hate them; used to like Bookie, now I hate them; used to like Bangel now I hate them. The list is endless!

Well recently it happened with Will&Emma, I loved them at the beginning, now they're just mehh to me ;/

almost always
I used to like NavAde , Liomi , Stelena , Chair - now I hate all these couples

I HATED Puckleberry, now I'm open to the idea. I wasn't fan of Serenate, now I like them. Didn't like Jeremy/Anna, then I freaking adored them.

I loved Ryan/Marissa, Leyton, Clana, Dawson/Joey, Derena, and Ross/Rachel, but now I hate them.

im with sk91, it doesnt happen with couples i LOVE or HATE, only with couples i just recently started liking or disliking, i just stop caring about them lol, like will&emma on glee i really dont care what happeneds to them but initially i really liked them. and finn&quinn, i was all about puck & quinn, but latley iv been liking the idea of finn still having feelings for quinn lol. the overratedness of a couple can change my opinion on them too, cough*damon&elena*cough. lol i loved the idea of them, now i cringe when people mention them.

for me i eith love a couple from the beging or i hate them.

I used to quite like Brooke and Julian and completely despised Leyton, they made me sick just watching them :P but now I'm more tolerant of Leyton (although in no way does that mean that I like them :/) and I absoloutely hate Brooke and Julian. I aslo loved DL in CSI NY and now I can't stand them :P

It's happened with couples that I once adored like Chuck/Blair - I don't dislike them but I just don't care the way I used to. Same with couples I used to hate now I'm mostly indifferent to them except a few. (Jate, Bill/Sookie) Still hate those two, lol.

When I just start to like a couple and the storyline doesn't attract me, then I become indifferent to them.Like for Serenate, I used to love the idea of these two together but after S3, I'm glad that they broke up.

Once I like a couple I generally always ship that couple. But although I have always liked NB, there were times I didnt hate CB.

Very rarely.

if i tend to like a couple i'll stick with it till the end

It really just depends on the writing. If their storylines go to shit, I stop caring about them.

I used to love BL *guilty* and now I hate them! That's the most significant change, I think! But there are also a lot of couples that just grow on me...

I used to love NavAde now they bore me.I used to dislike Brucas,now I like them.I used to hate every couple that had to do with Vaness(from Gossip Girl) and now I love all(Natessa,Channessa and Danessa).I used to dislike Jate,now I like them.I was open to the idea of Brulian in the start,but now I absolutely hate this couple with a buringn passion.And I'm sure there are more examples....

But don't ask me which!

soemtimes I lose interest but I rarely change my mind all together

I loved Ryan/Marissa, Clark/Lana, Dawson/Joey, Buffy/Angel, Buffy/Spike, Rory/Dean, Laurelai/Christopher, Piper/Leo, Phoebe/Cole, Seth/Summer, Lucas/Peyton, Nathan/Haley, Jack/Kate. Mostly I liked them from the pilot and I never changed my mind. I might have started to like and accept couples like Joey/Pacey & Laurelai/Luke but I will always love the original couple.
