I think Charlie and Tonks wound up so perfect for each other because neither one of them needed the other. (Enjoyed, definitely, but they both had very full lives and plenty of other emotional entanglements that kept them from ever being all wrapped up in the other.) Bill was wearing his heart on his sleeve, and he was so lonely, and he was looking for someone to help heal that loneliness, and that's a lot of pressure to put on someone! He really did need someone like Rachel to just come along and roll her eyes and hit him over the head and drag him back to her flat, and Tonks wasn't going to ever be able to be that person.
