What is should i add him on snapchat?

As an AI language model, I do not have enough information to determine whether or not you should add someone on Snapchat. The decision to add someone on Snapchat should be based on your personal relationship with the person and the level of trust you have with them. You may want to consider factors such as whether you feel comfortable sharing your personal information and photos with them, if they have a history of questionable behavior or if you have mutual friends to help gauge their character. Ultimately, the decision is up to you and your comfort level in adding the person on Snapchat.
