I have been dating this girl for three weeks now. She has not been answering my text lately. We spoke during the weekend and everything was fine and we even made plans to meet up during the week. I remember she told me she was going to be on her period this week. Also, on our first date, she told me she was a bitch when she was on her period. Do you think she is not answering because she is on her period or is she not interested anymore?
