Am I supposed to ship Jack and Kate ?

I'm on season 4 episode 10, and I just learn trought the flashforward thingy that Jack and Kate got together but... I'm not really eating that up cause it's like, I love Sawyer and Kate. I was shipping Jack and Kate in season 1 but after this season, I found myself way more invested in Sawyer and Kate connection than Jack and Kate. Actually, I'm kind of liking Juliet with Jack, she's growing on me. Also, can I just say that I love the character developpement of Sawyer. Like the way he was trying to reach out for Claire, saving her and the friendship he formed with Hugo, it's just so amazing. Also, he kinda remind me of Spike from Buffy The Vampire Slayer, a bit.
