So my gf of two and a half year gives me strange vibe.

She'll come to the town where we study on a college with her sister on 12. and will stay for two nights. Her sister will stay with her boyfriend and she will stay with me for the duration.

On Friday (15.8.) she told me she's going out (GNO) in her home town and while she was saying it (over text) she wrote like four reasons as to why it would be problem for me to come also (You'll spend money, you have nowhere to spend the night, I don't want you to hassle because of me, etc.)

May be important: Last year she invited me to come to her town for a party, I did, we had a great time but when I drove back home I was somewhat angry because I didn't like that she couldn't arrange something for me to sleep over her house (she lives with her parents). And she used it now for an argument (You said that you won't come party here unless you have a place to stay so...)

I don't know whetever should I call her out on this or not. Help and advice needed.
