There's this girl I like and I'm not sure if she's bi/lesbian too. We only have one class together and it's every other day. I don't want to ask her if she's because I don't want her to say no and not talk to me again how do I deal with this?
The best relationships are based on friendship and if you become friends with this girl, you’ll get to know her well enough to know the answer to your question. Maybe you’ll end up dating or maybe you’ll just gain a new friend, but either way, you win.
Don't be shy! Say what's on your mind and get a good dose of perspective in return.
