Did Mina cheat on sonic with ash?

Answer 1

During her crush on Sonic, Mina seemed somewhat oblivious of the hedgehog's true feelings for her and for Sally. When she realized that he and Sally loved each other, she suffered tremendous heartbreak.

When Sonic was thought to be dead, she eventually entered a relationship with Ash, manager to her musical career. However, upon Sonic's return, she became conflicted in her feelings, causing Ash to be hostile towards Sonic. Realising she was causing Ash to be insecure and that her behavior was selfish, she sent a letter to the Ask Aly column in the local paper. Sally (using Aly as her pen name) suggested she still give Ash a chance to see where her true feelings were.

Mina decided to follow up on this advice, but when the mongoose was targeted for assassination by Eggman, Sonic was assigned as her bodyguard, furthering her conflicted feelings. Ash, hurt, eventually confronted her, claiming that even her songs seemed to be about the hedgehog. He asked her to say that she didn't love Sonic anymore, and when she couldn't bring herself to do so, they decided the relationship was over. However, an attempt on Mina's life was once again made, and Ash selflessly saved her from a bomb, gravely injuring himself. Distraught, Mina stayed by his bedside, and when he awoke, she admitted that while Sonic would always have a place in her heart but the incident made her realize she truly loved Ash.
