Good evening, all. For some reason when I'm in a group of people with girls, I can talk to any girl about anything and I'm super confident, but when I'm alone with the girl or meet her for a date, I get really nervous. I'm not trying to impress her and it doesn't affect what I say, but I just get really nervous like my heart speeds up and I just feel really awkward. Sometimes I think it might be because deep down I know that she's not into me...
