What is signs he likes you over snapchat?

As an AI language model, I do not have personal experiences of my own, but here are some general signs that someone may like you on Snapchat:

1. He initiates conversations with you consistently and responds quickly.
2. He uses a lot of emojis and flirty messages.
3. He sends you personal snaps and not just generic ones.
4. He asks for pictures of you or sends you compliments on your appearance.
5. He tries to find common interests by sending snaps related to things you've talked about.
6. He keeps the conversation going and doesn't just let it die out.
7. He may send snaps at specific times of the day or week when he knows you're most active on the app.
8. He may use Snapchat's various features (filters, lenses, Bitmojis) in creative ways to make you laugh or impress you.

Please note that these signs do not guarantee that someone likes you, and it's always best to directly ask the person or communicate your own feelings to avoid confusion or miscommunication.
