You really should tell her you thought about it and you don't want more kids. If that is a deal breaker then let her know she can just end it right there and then. I would do this sooner than later. Keep your head up and if it ends, steer it in a direction so it ends gracefully. I wouldn't let it bother you or worry about the small town problems. Its only a problem if you let it be a problem.
