Hi
Others might interpret this differently but I say it's a
good thing that she is asking for some time apart! This means she's seriously thinking about the relationship, where it's going and whether or not she wants this to be the real thing. She could easily just stay with you every day as you have been doing and keep going with that, then leave when she gets bored, but she's actually talked to you about having more space to figure out something as important and life-changing as you being "the One"!
Give her the space and while she is thinking,
you do some thinking too. Make sure that you know she is The One, then when you come back together, your love will be stronger and the relationship .... stronger too
I can't help with scripture sorry, someone else may be able to.
As for her friends inviting her to college - if she has been spending heaps of time with you, she might just want to be with her friends for a few days. It's not that she wants to run screaming away from you, she just wants to be with some friends and be one her own for a while - we all need our alone time.
The best thing you can do right now is to support her and use the time wisely to think about your future with her and if this is really what you want. Then, if the relationship is "the One", you will come back together and keep moving on. Don't keep phoning her etc or pressure her into "making a decision". Give her some space but let her know that you are thinking of her and still there for her.
Why don't you go see some of your friends and enjoy yourself? Use the time apart to visit people you wouldn't have seen for a while, or who you might have put on the back burner while you were with your girlfriend. Don't think of it as a seperation - you are still dating, you're just not in the same place at the same time.
Hope this helped a little bit!
