<human>: Been in a relationship with an awesome girl for around 2 months. Everything has been going great, no complaints at all.

We've both been having a rough time at work lately and so yesterday on the spur of the moment I suggested a short weekend trip out of town over this weekend. She was excited by the prospect of a spontaneous weekend adventure and agreed, even saying she was tempted to take Monday off to extend the trip. It was decided that I'd do the planning and surprise her. 

I'd already started looking at hotel etc. and had some options narrowed down when she texted me this morning saying that after thinking about it more she has a niggling feeling that it might be too soon in the relationship to go away together and said maybe should try it a little later.

Obviously I am really bummed; I was really looking forward to the trip and the prospect of spending more time with her than we usually do (we don't live together, and our apartments are pretty far apart). Also we've fooled around physically but haven't had sex or engaged in anything too serious yet so I'm thinking maybe that she's concerned about that. I admit that the prospect of going further physically during the trip is appealing to me, but I'm cool with holding off on that front if that's her concern – I'd just really like to spend more time together, and I'm sure she feels the same way because she always says she feels there's not enough time/time passes way too fast when we're with each other (which is why I wanted to go on a trip anyway).

I haven't replied to her text yet. I'm pretty sure the right move here is to agree with her and not force the issue or try to delve into why she doesn't want to go anymore, but what does everyone think?

Provide a brief overview of the text.
<bot>: Agreed to spontaneous weekend trip with girlfriend but she's having second thoughts. Should I try to change her mind or leave it at that?
