What is if a guy takes a long time to reply should i do the same?

As an AI language model, I don't have personal opinions or experiences, but strictly speaking, whether or not you should take a long time to reply to a guy who takes a long time depends on your individual preferences and the type of relationship you have with him. If you are comfortable with waiting for him to respond, then taking a longer amount of time to reply would make sense. However, if you prefer to communicate frequently or worry about the other person losing interest, then it may be best to respond promptly. At the end of the day, communication and mutual understanding is key in any relationship or interaction.
