In the main-canon of the games by Sonic Team, he is still too young to marry though it has been hinted several time that he has romantic feelings for Amy, it is easy to note he stopped running away from her after Sonic Unleashed.
In the non-canon Archie comics, he marries Sally Acorn and has children with her named after his siblings in the Sonic Underground continuity, Manic and Sonia.

Yes, in the Sonic Comics it mentions that Sonic will marry Sally acorn and have 2 children 30 years from now.
Amy Loves Sonic the Hedgehog! Amy plans to marry Sonic. But Sonic only likes Amy as a friend.
There is no youtube video about who Sonic characters marry in the future. I researched and found this web: http://archiesonic.wikia.com/wiki/Category:Mobians In this website you'll see ALL Sonic characters from the past, present, and future. You'll see who they marry and their children. I hope I answered your question.
Well, the big reason is because both of them are too young to marry. Back in the Classic and Dreamcast Era, Sonic is irritated by her, always chasing him or hugging him. However, Sonic has stopped running away from her after Sonic Unleashed came out and he has shown some feelings towards her from then.
