I met up with a girl last Wednesday and we really seemed to hit it off. She seemed very affectionate and even offered to walk me home in the rain (which I politely declined to). I then asked her on Saturday if she was free later, she said maybe then about 5 hours later said she had to take care of a friend's dog. That felt like a lame excuse but I just said maybe next time and have fun, to which she just responded thanks with no indication of wanting to meet up again. Was she just being polite? I'm confused as to why she'd say maybe if she really meant no. Should I try to text her in a week? I'm really confused.
