When it comes to understanding if your partner is feeling jealous when you talk to other women, there are a few signs to look out for:

1. Increased Monitoring: If she starts obsessively checking your phone or social media accounts, or questions you extensively about your interactions with other women, it may be a sign of jealousy.

2. Overreacting: If she overreacts or becomes overly emotional when she sees you talking or even just being friendly with other women, it could indicate feelings of jealousy.

3. Withdrawing Affection: Jealousy can cause a person to withdraw their affection as a means of protecting themselves. If she becomes distant or less affectionate after witnessing you interacting with other women, it may be a sign of jealousy.

4. Passive-aggressive Behavior: She might make snide remarks or act passive-aggressively towards you or the women you speak to, as a way of expressing her jealousy and frustration.

5. Increased Need for Reassurance: If she frequently seeks reassurance from you about your feelings for her or your commitment to the relationship, it could be because she's feeling insecure due to jealousy.

If you notice these signs, it's important to address the issue with empathy and open communication. Here's how you can handle the situation:

1. Listen and Validate: Let her express her feelings without judgment. Show empathy and understanding by acknowledging her emotions and assuring her that you care about her.

2. Reaffirm Your Commitment: Reiterate your love and commitment to her. Remind her that talking to other women doesn't diminish your feelings for her and that you are fully committed to your relationship.

3. Set Boundaries: Discuss and establish healthy boundaries within your relationship that both of you are comfortable with. This can help alleviate any insecurities and build trust.

4. Encourage Open Communication: Encourage her to express her concerns or insecurities openly and honestly. Create a safe space for her to discuss her feelings and fears without fear of judgment.

5. Offer Reassurance: Take the time to reassure her regularly. Show her that she is valued, loved, and that your interactions with other women are purely platonic and harmless.

Remember, understanding and addressing jealousy requires patience, understanding, and effective communication.
