<human>: When I started dating my girlfriend 2 years ago, she was a freshman at community college in our city and would talk about how she was leaving in 2 years to go to school elsewhere. Since a lot can happen in 2 years (didn't even realize we'd last this long), I just kept going with it and put it out of my mind. I even put it out of my mind until about a month ago, when the time came to really talk about it. 

I'm deeply rooted here, and she's ready to move on from this city - she's been here longer than I have, and most of her original friends here have already moved on. She doesn't want to stay, I don't want to leave, and we both don't want to do a long-distance relationship.

She will be leaving as early as June, or as late as August. It's up in the air right now, but she'll know for sure by May.

We both want to stay together until then, and "enjoy the time we have left". But there are some moments where it really hurts because I realize we're living in a fantasy relationship - it's coming to an end. Part of me says yeah, it's going to hurt anyway so just get on with that hurt now. Part of me says I can't choose the hurt when she's gone, but I can choose to not hurt right now. I'm not sure which is the best decision for me personally, but I wanted to see if anyone has been in a similar situation and can offer advice.

For the record, our relationship has always felt a bit "casual"; she wants kids, I don't. We wouldn't feel good marrying eachother, I don't think. We sort of knew what it was when we started. We only see eachother once or twice a week, we don't really take a lot of big trips together or anything.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Girlfriend and I are going to split up when she leaves for school this summer. Better to do this now, or just wait until she's gone?
