I told a girl "I didn't want to be lead on" even though we agreed to a casual relationship. She messaged me back a couple of hours later saying that we want different things from this relationship and then she told me she didn't want to "move on" because of a past relationship but she told me that she enjoyed all the time we spent together. I have no clue why but I decided to agree and now I realize, 3 days later that I made a very big mistake. How do I bring it back up that i just want a casual relationship. We started this a week ago (lasted 2 days)
P.S - I'm going out for lunch with her and her friends this upcoming weekend.
