Only she can answer these questions. Ask her, if you and she are truly friends then you need not be afraid to ask.
I find this question confusing, as you say you are a lesbian and your friend is gay...yet you are attracted to each other..
If you are a female as well.
shes really not a best friend if shes going out with her best friend's crush new person! i object wat if she was dating him first then the other best friend got the crush!?
Tell your friend how much you love the person and promise the friend never to disappoint and that you wont tell your crush where you got the number
If your best friend liked him/her first, then let your best friend have a chance at dating said crush. If things don't work out for them, ask your best friend if it would be okay if you flirted with/dated him or her and act accordingly.
Considering you're female, you may be. However, you may also be fond of males as well. So, you may be bisexual instead.
1. If you're a lesbian too, and you two have been flirting and all that, then ask her out. 2. If you're a male, and she isn't bisexual, then you're most likely out of luck.
lesbian
That really depends on what that secret is... If you want to say that your gay or lesbian wait untill your drunk:) if its a crush... He or she is your BEST friend if they really are they will not tell anyone. Hope i helped !
If she's really a lesbian, then she can might be able to have a man-crush on you (also called a "bromance"), but not an intimate or romantic crush.
Dance!
That depends on wether or not either of them knew of your crush.
