So a while back I(31m) started talking to a girl(19f) at work. She is smart funny mature and all together an amazing woman. I talked to her more and more to find something some reason not to date her beyond her age. We like the same type of movies and a bunch of things like that. We want the same things for our future. I ended up asking her to a museum after a couple months. She asked when? The date went fantastic. Museum home cooked meal and movies it was just perfect to us both. We are doing great. Now the fear I am hoping some people in this subreddit understand. I am scared one day she will outgrow me or worse look back and hate having wasted her youth with someone a decade older than her. Honestly though even if I knew that would happen I want to enjoy all the time together till then. What do y'all do about that fear? Or is it just me?
