When my girlfriend of the time (now my wife) and I first went away to Vegas for a weekend she had talked about how much of a good time we were going to have there. She has a tendency when stressed or upset to get diarrhea. By the time we checked in, she had diarrhea. When I went to the hotel gift shop to get something for the diarrhea and she saw the receipt for the over-priced product, she got upset that I spent over $10 on a small bottle of Pepto-Bismol (20 years ago.) We did eventually have a nice time in Vegas. The sex was no better or worse than back in our respective apartments. And we did get married… Here is what I have learned about sex - trust no promises of future bliss. Often it just doesn’t turn out up to expectations. Sure you should have plans and enjoy things together, but beware that things don’t always turn out like either party imagined.

she's just not that into you but she wants you to take her on vacations. she's using you. sorry op
