<human>: First time posting to this subreddit, I have a girlfriend who I met during my freshman year in college three years ago(it's a decently serious relationship) but I met a girl at a party last night who came with her brother and boyfriend but seemed a bit interested in me(she started talking to me around them and it felt like the situation was more significant than just run-of-the-mill chat especially as a girl who came to the party only knowing her brother and boyfriend) and now I'm not sure what to do.. She asked for my number and I gave it to her so we could "talk more.." but should I wait for her to say anything to me before I text her or initiate something that could be interpreted as something more serious? Im not sure whether or not she's just interested in me as a friend or if she wants something more =/ She seemed like a unique, interesting and fun person and I think would be fun to talk to but should I risk it affecting my current relationship?

Can you condense the text into a few key points?
<bot>: I met a girl at a party that is cute and nice and seemed interested in me but I am currently in a relationship and plan on maintaining that relationship, is it worth texting her at all, as a friend or anything?
