Based on their Personalities

I'm just stating my opinion based on these two characters.
As MUCH as Archie wants to shove it down people's throats, Sonally isn't a very realistic coupling.

Their personalities are more opposite in a way that fundamentally they wouldn't be able to work out.
Even with the usual "opposites attract" myth, the people in the pair have to have some parts of their personalities that is flexible enough to deal with their partner's traits.

But just the basics of Sally being a more "consistence" based character (She would like consistency as well as being in command) couldn't ever really cope with Sonic's free spirited character.
It's preposterous to think that Opposites attack is going to cover the difference either. People need to understand exactly what opposites attract REALLY means before they start banking on it <____<

I think I am also backed up by SEGA on this too (And Former SEGA in Yuji Naka's case):
Naka has said that he can't ever see Sonic settling down for example.
Sally's the type of person who would NEED to settle down based on how she relies on people as her support.


Further Ranting:

Sonic even GIVES us the reason he shouldn't have a girlfriend in the comic!
"He wouldn't have time for his friends"

I am a fan who hates the idea of Sonic really having a steady relationship. I really am. Although I feel that if he DID have one, Amy would be his best choice, I think he shouldn't unless it's needed.
And do you guys know why this is so? It is very simple.
His character.

Sonic is a character that is BASED ON FREEDOM. That is all that Sonic is based on. Freedom is his life, and his motive. And it takes the form in his being not only a hero, but simply the "world's fastest hedgehog".
The reason that he loves running is the feeling of freedom that goes with it.
In truth, freedom is sorta what makes Sonic, Sonic.

So please, can somebody tell me why it is that this character who IS based on freedom would even want to be tied down?
NOT having the blessing of somebody who is willing to keep up with HIM; but being tied down.

Because that is all that is going to happen with a certain Chipmunk character we all know I hate.
Sally Acorn is a character based on control. Have you guys noticed this? Sally is a person who grew up as a princess:
she was taught from a young age that she needs to be responsible, and she needs to be a leader. And she was also taught that in order for this to happen she needs to be in control of the situation. [I get this from who her father is: the guy who is continuously fighting to keep control on his former kingdom even now]
Sally is always proclaimed as the strategist; this would have ALSO contributed to her need to be controlling of the situation.

But that is not all. Recently Sally's development has shown that Sally is the type of person who needs people to be there for her. She depends upon people and she is insecure about loosing people she cares about.

Those two traits: Controlling and Possessive/Dependent are what makes up her character.
And so that leads us back to my question:

If this chick IS a controlling and possessive person, then why the heck would a guy who is all about FREEDOM and INDEPENDENCE want to be in a relationship with her?

It does not make sense.
It will never make sense.
People will try to argue that they are supposed to be able to "compromise". Yeah: No. Sit Down.

Sonic is many things, but he is never a compromiser. He doesn't WORK like "Okay, I see both sides now I'll find an answer".
He is the person who will run into trouble without knowing or caring about what side you are on as long as he is doing what is right.
He will not change for another person.
It's not going to happen.

But it is also not likely to happen with Sally either.
Although Sally is supposed to be able to be level headed and compromising, she has shown that there is a limit for her.
Take the slapping scene where she calls Sonic selfish for his choosing his lifestyle over her.
She can compromise when it comes to policy or government, but emotionally she isn't quite that capable.
