<human>: This might be completely stupid and lame but here it goes. I like this girl, lets call her Sarah for this post's sake. Sarah and I have been really close friends for sometime and we have shared very personal things. I like Sarah and I am 99% sure Sarah likes me back. 

Since I am the man, I would need to ask her to be my girlfriend, but the major problem is that she is a year old than me, meaning that she graduates a year sooner than me. My greatest fear in my life comes the month where she will be leaving college and I will be stuck here. And before someones says that she could be in the state still after college and have a relationship with me, this is highly unlikely. 

I just want to show her how much I care for her and love her so much. I really just want a way to say that I would ask you (Sarah) out but I fear the day when you will have to leave me. And I do not want me or you to go through that pain and sadness. Can someone help me what to say to this girl or what to do about this whole thing. Thank you!

<bot>: I want to show this girl how much I care for her, but the real fear of leaving her eventually is stopping me. I want to tell her why I have not asked her out etc.
