Hi Angel,
If you can look at this as a way for you to get better on dates, then, there is no harm in meeting up with her. If she is actually willing to meet up with you, it’s unlikely that she is completely against the idea of finding a romantic partner.
After all, she chose to join the dating app. It’s just that, at this point in time, she doesn’t want to deal with the pressures and responsibilities of a full-fledged relationship.
As long as you are able to go to the date without any expectations of her changing her mind, you will reap the benefit of gaining more experience, which never hurts. The more you learn, the closer you get to finding the right one for you.
