I've been hanging out with this girl lately (who is also lesbian) & I'm having a hard time discerning whether she's attracted to me or just wants to be friends. How do you tell if someone is interested in you "that way"?
At the risk of being completely unhelpful, this. But I'm probably saying that because I'm not good at telling when girls like me. Guys, easy, girls... not so much. At least you already know she's a lesbian, so that's one obstacle out of the way. Try to see if she treats you differently than other girls. If she flirts with you -- lots of eye contact, teasing, smiles, touching. Her kissing you is also a good indicator.
