For whether it is necessary for the blind date to continue in a different place, this question needs to consider many factors.
First of all, be clear about your feelings and interests in this blind date. If you have a deep affection for her and feel that she is the person you want to spend your life with, then it is necessary to continue to develop the relationship even if you are in a different place.
In this case, you need to think about how you can maintain your relationship, such as through frequent communication, planning the time of meeting, supporting each other, and so on.
However, if you don't have particularly strong feelings or interests in the blind date, or you don't feel that your personality, lifestyle habits, etc., are not quite compatible, then you can consider stopping the relationship further. In this case, you can tactfully tell the other person how you feel, or choose not to contact again.
Also, consider the specifics of your location. If you are only temporarily in a different place and may live in the same city in the future, then there may be a possibility that your relationship will develop.
If your long-term situation is long-term, such as if you live in different countries or regions, then your relationship may be more difficult. In this case, you need to be more careful about whether you want to continue to develop the relationship.
In conclusion, deciding whether or not to continue to develop a long-distance relationship with a blind date requires a comprehensive consideration of many factors.
If you have a deep affection for her and believe that you can overcome the difficulties of being in a long distance, then you can choose to continue developing the relationship.
If you don't have a particularly strong interest or affection for the blind date, or if you're in a long-term relationship, you may need to be more careful about whether you want to continue your relationship.
