I told a girl I liked her....

Okay so let me start by saying that all my life I have dated men but I have had crushes on girls and never pursued them. So anyways when I was 15 I used to talk to a girl a met on Facebook and we would talk all day and night. I had the biggest crush on her but I was scared to tell her. She also lived in another state at the time. We eventually fell off and stopped talking but idk what happened. So sometime last year she hits me up to text her and i find out she has moved to my state and lives down the road from me. We communicated through text message for a little and fell off again. Then we recently started texting again maybe a month or two ago. And she asked me why i didnt like girls and then i told her i had girl crushes in the past but she was my first girl crush. Anyways i met her for the first time on Sunday and I had so much fun that I realized I was alittle bit interested. Last night my friend convinced me to ask if she liked me and I did which was dumb because she basically said she didnt know me (which i guess is true) and that she thought I was straight.. So anyways she made feel awkward and I was quite embarrassed. I havent texted her at all today. I feel so stupid for listening to my friend. I wanted to just tell her so she knows but its all new for me and im embarrased. Im 22 btw smh. So I decided I wanted to be honest with myself because I know I have had several crushes on girl but afraid to act on it. Anyways are there an pieces advice you can give me?
