<human>: Stats:
Her - 24
Me - 24, male
Relationship - Almost 6 months

So, recently, things haven't been going so swimmingly with my girlfriend - she's 24, as am I, though I am a male. Everything was going great before she went on a trip abroad around a month ago with her family. After then our sex life declined and, the other night, she told me she's been feeling vulnerable and that she doesn't even want me to touch her. She's also been crying a lot more lately. She says she doesn't know what's wrong with her and, honestly, I have no idea either. Admittedly, I haven't been handling it as well as I should be.

Can you condense the text into a few key points?
