<human>: Could you distill the essence of the text into 1-3 sentences?

First I'd like to say that this is my first real girlfriend. I've never met anyone I've connected with and liked so much in my life. I've dated many, many, many girls and this one just takes the cake.

That being said, I'm about to make a big change in my life, and pursue my dream of being a doctor. However my girlfriend will not be joining me, and she does not want a long distance relationship because she's done it before and she says it's too difficult.

I'd be willing to try it and when I asked her about it she does not want to try it out. At the end of the day, I have to do what's best for me, and I realize that if she's not willing to put the sacrifice and effort to try and be with me, then maybe she isn't the one for me and she isn't as committed to me as I am to her.

Have any of you been through this. Can you give me any words of advice on what to do, or at least on how to deal with letting her go?
<bot>: Girlfriend does not want to do long distance when I go to med school due to her past experiences with it. I however want to try it. Any advice?
