I've (29m)been seeing this girl (27) for a little over a month now and everything seemed to be going great. She even said everything is going great a few times. We went away last week and stayed in an airbnb for a few says and she was extremely happy and said how much of a good time she had. This week I've noticed she seemed a little less happy and I asked her if everything was ok and she always said yes. On the phone everything seemed fine. I was with her yesterday during the day we went to the mall and when I first saw her she said how much she missed me and that when I kiss her she feels so good. We were with each other for 4.5 hours and on the way home I noticed that she seemed to get a little cold be just slightly. After I dropped her off she kissed me and said have a good day. I texted her an hour later saying I enjoyed seeing her today. She didn't respond until this morning and she said exactly this "So many things I've noticed it's disappointing me. I hate to say this because I really felt a great connection with you." I texted her back saying I'm sorry to hear that I'm confused though. What is disappointing you. Does anyone know what this girl could possibly be thinking? And what should I do?
