What are you doing that might scare them away? You are who you are, and should not pretend to be what you are not. If it would scare them away then either a) you are doing something you shouldn’t or b) they need to chill a little, because they are overreacting, in which case it probably would not be the right shidduch for you to begin with. Based SOLELY on the way you expressed your question, I would tend to think you are aware that you are doing something you probably should not be doing, or you would not be worried about it having a negative impact.
Or I am overreacting.
