<human>: My GF has been with her parents on a vacation for a month and we haven't gotten to spend any holidays together. I've seen her family only twice since we've dated. She's coming back in 2 weeks and just told me today that I "might want to look at flights because they have some cheap deals," and that she wanted to visit her grandparents (who are very ill). 

I told her I'd love to go with her (and even offered to pay) and see her grandparents. Last time I saw them, we got along really well and they told me to come visit. 

She told me that she wanted to take the trip alone and have a couple days to herself, and gave me no explanation why except that she "wasn't trying to offend me" and thought telling me she made plans without me would be better than just going and not letting me know. I don't really understand this.  

I told her that I'd be there for her support and that I haven't seen her family in awhile...then she said she didn't want me to come because they're so sick...and I said it's no worry, I would love to help take care of them. Then she told me they don't need to be taken care and they're not that sick but she would rather I come when they aren't ill...that she is just going to be visiting and "going shopping" and stuff like that. 

She said she wants to go with me when we can go longer than two days...but I told her I can't really take a whole week off work and two days is the perfect time (flights are only 20 bucks for that weekend too). Also, she's going literally right after she gets back from her vacation. 

She made the plans a few weeks ago and didn't tell me about it until now...which I also don't understand. I kinda have hurt feelings, and she really gave me no other explanation than "I'm not hurting you. I just want to go alone."
