It's natural to feel confused and uncertain about someone's behavior, especially when it comes to matters of the heart. In this situation, it's important not to jump to conclusions or make assumptions without clear communication.

First, it's essential to recognize that absence or lack of communication doesn't always mean disinterest. There could be various reasons why she hasn't reached out, such as personal issues, family circumstances, or any other unexpected events. It's crucial to keep an open mind and consider other possibilities before making a decision to forget her and move on.

To gain a better understanding of her behavior, it's necessary to have an open and honest conversation with her once she returns from her leave. Express your feelings and concerns in a non-confrontational manner, and ask her about her intentions and feelings towards you. Clear communication is key in any relationship, so make sure to give her an opportunity to explain her side.

It's also essential to remember that actions speak louder than words. While her intense looks, smiles, blushing, and fidgeting indicate some level of interest, true emotional connection and commitment require consistent effort and communication. If she is genuinely interested, she should make an effort to reach out and maintain contact, even during her leave. However, it's essential to gather more information through a conversation rather than making assumptions.

Ultimately, the decision to forget her and move on is up to you. If her behavior continues to leave you feeling confused, neglected, or uncertain about the potential for a relationship, you may need to consider your own emotional well-being and decide if waiting or moving on is the best course of action for you.
