I met this girl a couple weeks ago, we had a nice conversation and everything went smoothy. But I lost her number but I found her on facebook, but it turns out she has a boyfriend. At first I thought "Ah no point wasting my time, she's taken." The only thing we would really be is 'friends' at this point, and if you know me I am 100% against masquerading as a friend when you really want more. But I've been having second thoughts, and I've considered just hanging out with her. So what if she has a boyfriend, we can still hang out, she's attractive so it's social proof, and I might meet her friends in the process.
