It hasn't been confirmed yet by Sonic Team, so you'll have to wait, but it is more than likely that Sonic will eventually fall for Amy, as she is literally the only one who loves Sonic. It is impossible for Amy to marry Shadow, because if she were to grow up as an adult, Shadow will still have his teenage appearance as he is immortal.

It is possible she is going to marry Shadow and her son is going to be Silver. It is possible!!! Actually, it is not possible because Silver and Shadow are from different eras. Silver comes from the far Future, about 100 Years after Shadow's debut. So, no, Silver is not Shadow and Amy's son. - The Sonic Maestro
The reason is that they're rivals is cause sonic likes Amy and shadow likes Amy too
Shadow doesn't like her but Amy likes shadow and sonic she has to deside so it's best to like sonic though cus shadow is just a recreation of sonic so i thank sonic and Amy are better together.
