If a girl leaves a message on "seen," it means that she has read the message but hasn't responded yet. Here are some things you can consider doing in such a situation:
Give her some time: People might leave messages on "seen" for various reasons, such as being busy, not knowing how to respond immediately, or needing time to think about their reply. Avoid jumping to conclusions or assuming the worst.
Be patient: Give her some time to respond at her own pace. Don't rush or pressure her into replying quickly.
Avoid excessive follow-ups: Sending multiple messages in quick succession or repeatedly asking why she hasn't responded can be overwhelming and might push her away. It's best to be patient and wait for her response.
Continue with your day: While waiting for a response, carry on with your daily activities and interests. Don't let the lack of an immediate response consume your thoughts.
Send a follow-up message (if necessary): If a significant amount of time has passed, and you feel it's appropriate, you can send a friendly follow-up message to check in on her. However, avoid being accusatory or expressing frustration in your follow-up.
Be understanding: Remember that people have different communication styles and response times. Some might be more prompt in replying, while others take more time. Being understanding of this individual difference is important.
Don't take it personally: It's easy to overanalyze a "seen" message, but there could be various reasons for the delay in response that have nothing to do with you personally.
Respect her boundaries: If she is consistently leaving messages on "seen" without responding, it might be an indication that she is not interested in engaging in further conversation. In such cases, it's best to respect her boundaries and avoid pushing for a response.
Remember that communication in any relationship, whether it's a friendship or a potential romantic interest, requires mutual respect and understanding. If she does eventually respond, approach the conversation with kindness and interest in getting to know her better. If she doesn't respond or continues to leave messages on "seen" without replying, it may be a sign to move on and focus your attention on other aspects of your life.
