Rebshidduch – your original posts on this topic were about how you were concerned that you would end up dating this guy and you wanted chizuk to not do so. So don’t criticize the people who are trying to do just that.
In terms of this girl, it would be incredibly rude for you to stop giving her rides. It is also highly inconsistent with the fact that you have posted about how doing chesed is so important to you and that is why you were giving this guy rides even though you were concerned that you might end up dating him. This is your opportunity to do a true chesed – helping someone else out even when there is no personal gain and when there is in fact, an inconvenience. If you are truly a baalas chesed, you will continue to give her rides. And when people call me as a reference for you for shiddduchim, I will be sure to let them know what a baalas chesed you are, b”n!
