<human>: We've had a great relationship for 2.5 years. We have lived together for 1.5 years. We have been talking about getting married for a while, but I've always put off the topic. I love her a lot, but I feel like I'm too young. I feel so scared about getting married, and feel cornered. If I don't go through with it then she will maybe have to go home and her parents will have a horrible opinion of me most likely... possibly preventing us from staying together in a long distance relationship.
She has been a great partner for the last 1.5 years and I don't want to lose her. If I was stuck here alone then I would become miserable. I've never made such a big decision. I can't really say... oh well we'll get married and if it doesn't work out then "oh well". It's a life long commitment and that scares me.

<bot>: Maybe getting married to a girl I love, and if I don't she has to go home and we might break up.
