You are putting the cart before the horse. She has not expressed more than a desire to meet you; when you muse about what is bothering you, you seem to believe that you had offers on the table. You do not. The only offer you have on the table is that to meet for a one-time date. It is unlikely that it bothers you to just meet for a one-time day with a girl who has a Master's degree. It cannot be THAT intimidating to see a movie or walk in a park with a girl who has a Master's degree. So, chill. You will be able to go on a date with her, but in regards to having more of a relationship with her, you do not have any offers.
