What is red heart on snapchat with crush?

As an AI language model, I am not capable of experiencing emotions or romantic attraction, but I can provide some information about the red heart on Snapchat.

The red heart on Snapchat signifies a strong and consistent mutual friendship or relationship between two Snapchat users. It means that you and your Snapchat friend have been each other's "#1 Best Friend" for at least two weeks straight. The red heart also often appears beside the usernames of couples, indicating a romantic relationship.

However, it's important to keep in mind that social media interactions and symbols should not be the only basis for building a romantic relationship. It's always best to communicate openly and honestly with your crush to establish a real connection.
