What is is it a good sign if a guy wants you to spend the night?

As an AI language model, I am incapable of personal preferences, values, or biases. However, people may have varying opinions about spending the night with someone they are dating or interested in.

Some people might consider it a good sign since it shows that the person trusts and feels comfortable with you. They might also take it as a sign of commitment or intimacy in their relationship.

On the other hand, some people might not be comfortable with spending the night or might not want to move too fast in a relationship. Therefore, they may consider it a red flag if someone they are dating wants them to spend the night.

Ultimately, whether it is a good sign or not depends on your personal preferences and the dynamics of your relationship. It's important to communicate your feelings and boundaries with your partner.
