If a girl is open to various interactions and seems willing to engage in different ways on Instagram but is hesitant about sharing her phone number, it could be due to various reasons:
Privacy concerns: Some people are cautious about sharing their phone numbers online to protect their privacy and avoid potential spam or unwanted messages.
Trust issues: Giving out a phone number can feel more personal and intimate than engaging on a social media platform. The girl might be cautious about sharing that level of personal information with someone she doesn't know well.
Boundaries: She might have set boundaries for herself regarding how she interacts with people online. Engaging on Instagram might feel comfortable and non-committal, while exchanging phone numbers could feel like a more significant step to her.
Previous experiences: Negative experiences with sharing her number in the past could make her more hesitant to do so again.
Different comfort levels: Everyone has different comfort levels when it comes to sharing personal information. What one person is comfortable with might be different from another.
Fear of being overwhelmed: Giving out a phone number can lead to an influx of messages or calls, and she might not be prepared for that level of communication.
If you're interested in getting to know her better and she's open to various interactions on Instagram, it's essential to respect her boundaries and not push her to share her phone number if she's not comfortable doing so. Focus on building a connection through the means she's comfortable with on the platform.
If you want to take the relationship to a more personal level, consider other methods of communication that are less intrusive than a phone number. For example, you could suggest voice or video calls through Instagram's messaging features or propose meeting up in person if both of you are comfortable with that.
Ultimately, building trust and a connection takes time. Show genuine interest, be respectful, and let the relationship evolve naturally. If she feels comfortable and confident in the interaction, she may eventually become more open to sharing her phone number or taking the relationship to other platforms. However, it's essential to be patient and not pressure her into anything she's not ready for.
