Of coarse he likes misty just look at all of the clues in the episodes. It is plain as the nose on my face. Those two kids are the perfect couple and they both know it but they are too scared to tell each other about it.

I think that he loves her... I read somewhere that the author agreed with the fans about their "feelings".
I know the many clues and I am a Pokèshipper now and forever!!!!!

Even though she doesn't travel with him anymore, I bet Ash is still thinking about Misty somewhere inside his heart every day. And I also bet that Misty is thinking about Ash each and every single day.

DUH OF COURSE he's not going to let go of those feelings and dump her for one of those less attractive over emotional wimpy girls May and Dawn

Heck yeah he is xD

I think he's too dense to realize it, but he totally loves Misty

Ash is a little too immature to realize the feelings he has for Misty are those of love. He's not keeping a secret.. Personally, I think, the day Ash realizes he likes Misty, he'll randomly call out of the blue and say, "Hey Misty, I love you! Let's get together!" in his overexcited voice! xD
