My friend likes me... And I like her?

Yesterday me and my friend were texting and she pulled a "guess wat" on me and thats wen she told me that she had crush on.me. I told her I had a crush on her too. Now Ive liked her since Ive met her and she's really nice and I know she'd be good to me. Im scarred to go in the relationship tho. Im a lesbian and I know wat to do in relationships and stuff its just Im not sure if I actually.wanna be in one (i hope that made sense). I asked her did she want to hang out and all she said was hmm. Well it was pretty late. Anyway I do like her but I just dont know how to ask her out! I think she's shy so she's gonna wait on me to ask.but I dont know how CUS IM SHY TOO!! I really dont know what to do!
