Ginny would probably feel a great deal of guilt. This guilt could lead to her isolating herself from her friends and family. She might constantly be in her own head, replaying the events and thinking about how she could have made a different choice. Also, her reputation among the wizarding community in the fanfiction could be tarnished if the news gets out, and people might view her differently.
She might lose Harry's trust completely. Once trust is broken, it's very hard to regain, especially in a relationship as deep as theirs. Harry could become distant and cold towards her.
One possible consequence could be the breakdown of his relationship with Ginny. Ginny, being a strong - willed character, might not be able to forgive him easily. She could cut him out of her life completely, which would lead to Harry losing not only his love but also his connection to the Weasley family, who have been like a second family to him. Another consequence could be his own self - loathing. Harry has always seen himself as a good person, and cheating goes against his moral code. This could lead to him sinking into a deep depression as he grapples with what he has done.
She could also be very hurt and go into a state of deep sadness. She might isolate herself from Harry and their mutual friends for a while. Ginny would likely question her own self - worth and wonder what she did wrong in the relationship.

Some fanfictions might depict that the wizarding community might see her as a hero. However, others could show that she faces backlash from some conservative wizards who think she overstepped her bounds. They might try to isolate her at Hogwarts or spread rumors about her. But her friends like Harry, Ron and Hermione would surely support her through it all.
Another reason might be some kind of external influence, like a powerful dark magic that clouds Harry's judgment. However, this is often a stretch from the original concept of the characters. Fanfiction writers sometimes like to explore extreme scenarios to add drama to the story.
She could face the wrath of Harry. If Harry found out what she did, he might be really angry at her for interfering with his state of mind and violating his trust.
