My advice, Princess_Toph, save it for the fan-fiction . Your posts show that you actually hope/expect that Nickelodeon will pair SpongeBob and Squidward. It went past opinions a while ago, now you seem to be looking forward to it. So here are some things for you to take note of.
1. SpongeBob was stated to be asexual. Enough said.
2. SpongeBob showed signs of attraction towards a Krabby Patty. (Although you stated that can just be ignored since it was a non-living object, point 1 should already cancel the possibility of SpongeBob dating Squidward.)
3. In That's No Lady, Squidward shows signs of attraction towards a female... well, it was actually Patrick, but he didn't know that. So to him, it was attraction towards a female.
4. In Squid Bob Tentacle Pants, Squidward imagines girls cheering him on, and then they all carry him. He seems to enjoy it.
5. Nickelodeon is against showing homosexuality. I remember hearing in a Nick show, an episode was banned because it showed a girl/girl couple. But don't totally trust me on this one because I don't know the series, I just remember hearing something like it.
Lastly, SpongeBob is just a child, so that and point 1 are all that is needed to cancel the possibility of the pairing... Yeah, he did say he liked Squidward, but young people say stupid things often . If a child walked up to a guy and said he liked him in a goofy tone, I might not believe it.
And on the 1% chance that Squidward happened to be gay then come on, do you really think he'd like SpongeBob? Someone who bugs him to death? Think about that and the pairing seems all the more silly.
So basically, the evidence of them not liking each other is 10x's greater than the evidence of them liking each other.

Anyway, as for the topic, like I said, SpongeBob is asexual, and is fine remaining that way.
