It's possible that your best friend is not intentionally disregarding your request, but there could be several reasons why she hasn't completely stopped talking about her boyfriend or calling him when you're together. Here are some possibilities to consider:
Habit: Talking about her boyfriend and calling him when you're together might have become a habit for your best friend. Breaking habits can be challenging, even if she wants to respect your request.
Emotional attachment: Your best friend might be deeply emotionally attached to her boyfriend, and talking about him or staying in touch is a way for her to cope with the distance or to seek support and validation.
Lack of awareness: Sometimes, people might not realize how frequently they bring up a particular topic or engage in certain behaviors. It's possible that she is not fully aware of the extent to which she talks about her boyfriend when you are together.
Overexcitement: If your friend is in a new relationship or experiencing something exciting with her boyfriend, she may be overly enthusiastic and eager to share her experiences with you.
Social outlet: Your best friend might see you as a confidant, someone she can share everything with, including her thoughts and feelings about her relationship.
Communication style: Different people have different communication styles. Some individuals are more talkative and expressive, while others are more reserved. Your friend's communication style might naturally involve talking about her boyfriend frequently.
Relationship dynamics: It's possible that your friend's relationship with her boyfriend has an impact on her behavior. If they have an agreement or understanding about frequent communication, she might find it challenging to adjust.
What you can do:
Communicate openly: Have an honest and calm conversation with your best friend. Explain why you find it difficult when she talks about her boyfriend during your time together. Make sure your concerns are clear and non-confrontational.
Set boundaries: Let your friend know that you value your time together and would appreciate it if she could limit the frequency of discussions about her boyfriend.
Be patient and understanding: Change takes time, and breaking habits can be challenging. Be patient with your friend as she tries to adjust her behavior.
Offer alternatives: Suggest other topics or activities that you both can enjoy and talk about when you're together. This can help steer conversations away from the topic of her boyfriend.
Spend time with other friends: If your friend's behavior continues to bother you despite your communication efforts, consider spending time with other friends who may be more mindful of your preferences.
Ultimately, good communication and understanding each other's perspectives are crucial in resolving this situation. Keep in mind that your friend's behavior may not be intentional, and approaching the issue with empathy and patience can lead to a positive resolution.
