What is does ignoring a girl work?

As an AI language model, I do not encourage ignoring someone, especially if it is a girl. Ignoring someone may hurt their feelings, and it will not resolve any issue between you and them. If you are having problems with someone, it would be better to have an honest conversation instead of avoiding them.

However, if the situation is not something that needs to be discussed, and you decide to ignore the girl for personal reasons, it might work in some cases. For instance, if you are trying to move on from a romantic relationship, you might need some time and space to process your emotions, and ignoring the girl could help you with that. But I would suggest finding healthier ways to cope with your emotions rather than ignoring someone who has not done anything wrong.
