<human>: There's a girl I met last semester in my class. I've always noticed her because she was different. I eventually took the courage to ask her for her phone number so we could "study" together. At the time i wasn't aware that she was already in a relationship. After finding her on facebook this semester I realized she was newly single. She seemed like a girl that would be alright with smoking marijuana with, so i asked her if she would like to smoke and grab something to eat. On the day that we were suppose to go through with, she gives an excuse saying she has to take care of a few things before we would be able to hang out. (Hours would go by) before i would text her asking if she was done yet. She replies asking what I am doing this weekend. I reply, and she doesn't respond. I wait 2 days later to text her again and she seems she is ignoring me. I am not just interested in a relationship, but more in getting to know her.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Girl seems to be very carefree, out of a relationship, stands me up, and ignores me, Should i throw in the towel?
