It can be difficult to interpret someone's feelings, especially when their behavior is inconsistent. However, there are a few things you can consider in this situation.

1. Open communication: Talk to her openly and honestly about your concerns and feelings. Express your need for clarity in understanding her behavior. By having a conversation, you can create an opportunity for both of you to share your thoughts and feelings.

2. Pay attention to her words and actions: Look for consistency in what she says and how she behaves towards you. Sometimes, people may have personal issues or external factors that can influence their behavior, but if her actions are consistently contradictory, it may be a sign of mixed feelings or other underlying issues.

3. Trust your instincts: If you have a gut feeling that something is off or that she may not be fully committed to you, it's important to trust your intuition. While it's normal to feel jealous at times, excessive jealousy can harm a relationship. It's important to address your feelings of jealousy and work on building trust between the both of you.

4. Give her space: If she seems to be avoiding your presence or keeping a distance, it may be beneficial to give her some space. People need time and personal boundaries in relationships. Sometimes, stepping back a little can give her the opportunity to miss you and realize her true feelings.

5. Focus on yourself: It's essential to take care of yourself and your own well-being. Develop hobbies and interests outside of the relationship, spend time with friends and family, and focus on personal growth. By investing in yourself, you'll become more confident, which can help you navigate the uncertainties in your relationship.

Remember, it's important to have open and honest communication in any relationship. If you have tried to address your concerns and have not seen any improvement or clarity, it may be worth considering whether this relationship is truly fulfilling for both of you.
