It can be challenging to understand someone's true feelings and emotions, especially when it comes to love and attraction. However, there are some signs that can indicate whether she is jittery with love or genuinely annoyed by your presence. Here are a few things to consider:

1. Body Language: Pay attention to her body language when she is around you. Signs of jittery behavior could include fidgeting, blushing, smiling or laughing nervously, and playing with her hair. On the other hand, if she appears distant, avoids eye contact, crosses her arms, or has tense body language, it may suggest annoyance or discomfort.

2. Verbal Communication: Observe how she communicates with you. If she shows genuine interest in your conversations, actively participates, and maintains good eye contact, it could be a positive sign of her feelings towards you. However, if she responds with short, monosyllabic answers, seems uninterested in your conversations, or avoids spending time with you, it may indicate annoyance.

3. Availability: Consider her availability and willingness to spend time with you. If she frequently makes excuses to spend time with you, cancels plans, or avoids getting too close physically, she might be feeling annoyed or uncomfortable. On the other hand, if she actively seeks opportunities to spend time with you, initiates contact, and seems excited to be around you, it could indicate that she is jittery with love.

4. Communication: Open and honest communication is crucial in any relationship. If you are uncertain about her feelings, it is best to have a sincere conversation with her. Express your concerns and ask her directly about how she feels when you are in her proximity. Be prepared to listen attentively and respect her response, whether it is positive or negative.

Remember, everyone expresses their emotions differently, so she may have her unique way of showing love or annoyance. By paying attention to her body language, verbal communication, availability, and having open conversations, you can gain a better understanding of her true feelings towards you. Ultimately, it's important to respect her emotions and boundaries while nurturing open and honest communication in your relationship.
