Being a doctor means you sacrifice for others, and your family and spouse sacrifices while standing in the shadows of your career.
What do you think is a reasonable expectation for how much time you will spend together, how often you will talk, etc.
Glad I found this post. Most mormon girls look at guys like you as a project and that they have a lifetime to work on the project.
So if you feel like you both are getting serious, then talk to your girlfriend in time and sort this issue out.
