<human>: My girlfriend [21] and I [19] have been dating for around 6 months now and everything has been going great. I am the happiest I have ever been when I am with her and I know that she is very happy when she is with me too. She went to another state to visit some family (where she still is right now) and while she was gone idk what exactly happened, but she says she wants to go on a "break". 

"Breaks never work", "she's cheating on you", etc etc. I've heard it all and I know that she isn't cheating on me. She won't communicate with me about the reasoning for this break but I suspect it has to do with some family issues that aren't directly related to us together. I have been devastated and surprised by all of this because we are perfect together and I have never met another person anything like her before. I hope[d] to marry this girl one day (we have both talked about it) and I just don't know what to do. 

I KNOW that she still loves me greatly and is upset very much by this but I just don't know what to do. We have texted some since this happened, most of it very friendly but ultimately leads to me asking more questions about her reasoning and nothing getting answered. I know she wants to come back, and I'm hopeful she will, but there seems to be something stopping her. She won't let me help and is insistent on a "break" and she decided we wouldn't see each other when she gets back. 

My biggest concern is that this is meant to be a break-up and she is trying to let us both down easily while convincing herself that she can live without me (and I wouldn't put this past her even though it's not what she really wants). I've been struggling these past few days, bored out of my mind, and only thinking about her. I just don't know what to do. Help? Advice?

Give me the gist of the text in a nutshell
<bot>: Girlfriend still loves me but insists on "break" for unknown/unrelated issues and I'm not sure how I should react or what I should do. I love her very much and need some advice
