<human>: Summarize the given text in a few sentences.

I'm at school pursuing a degree, and so is my girlfriend. We are about to get engaged (we discussed getting the ring soon). For some reason I suddenly started thinking about "the one that got away". This is a girl that I was friends with before and we probably would have ended up being together if we weren't both leaving our hometown to go to grad school. She was a really good match for me (at least it seemed), especially in terms of lifestyle... where we would want to vacation, and what we like to do for fun.. our political views, etc. I was never actually with her though. It doesn't help that this person's parents are incredibly rich. I think that is what sparked thinking of her... suddenly I was thinking about my financial future when I remembered what it would have been like if I had ended up with her.

Reddit, if I end it it with my girlfriend she will have to go back to her country unless she finds a job. That's the reason we wanted to get married. Is it normal to be scared about getting married? I love my girlfriend and it would break her heart if I ended it... it makes me ill just thinking about it. Not only this, but the other girl in my hometown (3 hours drive away) is in a new relationship. If I wasn't thinking about this other girl suddenly then I wouldn't even consider being with anyone else. I'm absolutely desperate for advice. I can't talk about this to anyone else or everyone will be shocked.
<bot>: I'm going to get engaged soon and now I'm thinking about the one that got away. Want to know if this is normal.
