I know exactly how you feel. I went away to school about six months ago and became really good friends with my roommate. About two months after we met she came out and told me that she was lesbian. At that point I thought that I was straight but then I started having feelings for her and I think she had feelings for me. At one point we almost kissed. But we still haven't had a serious discussion about it. I really don't know what to do either. I don't know if I'm bi or straight and from reading the above comments I understand that I shouldn't assume I'm bi or lesbian just bc of this one instance. I FEEL YOUR PAIN. And if anyone wishes to give me some advice... go right ahead.
