Hi I have this friend who is a lesbian and I am a guy we hang out sometimes and well she seems like she is attracted to me and she told my friend the only reason she came to a party was because of me to see me so I'm confused I friend tell me she might not be a lesbian but bi but all I want is to get to know her and possibly develop a relationship with her. She's single too. She's really happy when I'm around and she always smiles at me and talks to me so I'm very confused.

Sure she likes you. How much, and how far that goes is for you to find out. Sexual orientation has little to do with personal attraction between humans but can define the nature of a relationship. Don't confuse initial human attraction or the notions of love because the differences are huge, but can be fun as finding out, as it is heartbreaking.

That's just the nature of any human interaction. Scary huh? Shy away from generic human labels though like gay, hi, or straight, as they are often subjective depending more on perspective, and perception, than accuracy.

Good idea to get to know the human as an individual though, before acting on just those initial attractions.
