Some background info: I am attending university first year, I live in a dorm. Last week my friend introduced me to two girls who are roommates in the same dorm as me. We all seemed to get along pretty well, one roommate even seemed interested in me further as she asked for my number and we have been flirting somewhat. Last week after meeting them we discovered that both me and both roommates share a class so we all went together. Today I was looking to do the same thing but when I texted the girl interested in me she never answered. Does this mean she isn't interested anymore? Is friendship even worth pursuing if she just never responds?
