Alright guys i need some help here. So i started going out with this girl about a week ago and everything was good she was texting me daily even texting me in the morning to say good morning and at night to say good night. Lately though shes been very cold. I think shes mad or upset at me but im not sure y. So on the night this whole thing started I had a meeting for work which lasted pretty late into the night and got home late. I texted her that i was going to bed and usually we talk on the phone at night. She asked me if I could wake her up in the morning and I said ya sure no problem. I got a text back saying that its ok ill wake myself up sp I said thats fine just text me if u need me to wake u up n this is where she started getting cold. She texted me back m i asked her if shes ok n she said ya so i told her im going to bed n good night n then she said BYE. The next day we were supposed to go on a date but she was like i dont really feel like it so we ended up just goin shopping n she was pretty cold. She wouldnt really touch me or look at me n barely kissed me. We sat down n i asked her what was wrong n she gave me some b.s. excuses about her life but i know she was pissed at me. I tried to get her to talk about it but she still wouldnt. I have had this happen to me in previous relationships can someone please tell me whats goin on n how can i deal with it?

She asked me if I could wake her up in the morning and I said ya sure no problem.
