<human>: Hey guys, I'm looking for some advice.

I work abroad, and met my gf there. She also works in the same city, and like me, lives in a different place than her parents. She hasn't been in a proper relationship in a while, and she (and her friends) told me it's strange her being in one and not like her. We both have finished work for the summer, and returned to our parents houses to go on separate holidays. Her travelling for a month, me travelling for 3 weeks. The travels clashed, with her returning 3 days after I left.

Throughout the time we've been apart we've been frequently talking, via whatsapp, and sometimes over skype, although voice chat hasn't been as frequent due to bad wifi.
Last week she seemed off, I just put it down to holiday blues, so to speak, and thought nothing of it, didn't push her too much on it and thought it would pass.

A few mornings ago I received a message from her, saying that she feels she has doubts about the relationship, that some things I've said to her in the past don't add up, and she's been thinking about it more since she got home and is now freaking out.

I genuinely couldn't (and still can't) think of a time where I have said something to her, that could be seen like this and asked her for some examples.  She said she can't remember anything that I've said like that, but knows I have. A discussion followed, where I tried to reassure her about how I feel etc.
Since then we have spoken, but not as frequently and she is still slightly off with me.

The main thing is that I am going to see her, and stay with her for 10 days next week when I return. Should I bring something up now and try to talk about it thoroughly with her before I see her, or wait until I see her in person?

Any help is appreciated, thanks

Can you provide a brief rundown of the text in within 3 sentences?
