Married and have a huge crush on a girl!!

I have already posted this under "later in life" so I apologize if you come across this again. I was just trying to reach more people who can help me. I am new here and I just wanted to share my story and get some advice. I am 21 and I have been married for a year and I've just been really confused and upset the past few days. All through my life I mostly considered myself straight,(strict religious upbringing) and now all of a sudden I have a crush on this amazing girl. She is a friend of my husband and she is into girls. I haven't met her in person yet but I am friends with her on Facebook. She lives in a different state. We both share the same interests and world views. I have yet to meet a girl like her; she is so unique and cool. She is tough, yet feminine. She is very funny and smart too, and did I mention she is awfully cute? I just think about her all day, even though I love my husband with all my heart and would never leave him. I am just so fascinated by this girl. A part of this could be that due to my family moving a lot, I don't have any best friends. I haven't had a female best friend in about 15 years! But with her, why is it different? How is my sexuality suddenly changing? I find myself extremely attracted to this girl. I think about kissing her a lot and cuddling with her, and sharing all our secrets. But it's not possible. We're going to be in that State soon so I'll get to meet her. I am really nervous and happy at the same time. My husband knows about my fascination and he has been such a help! He says it's normal and will pass... he is a great guy. I have thought about being with a girl before but I have never been with one. I am just very confused. Should I avoid meeting her? Because this could further fuel my fascination since I know we'll never be anything more then friends...
I wish I had the opportunity to date the same sex in the past. It was pretty much like a forbidden thing in my family. Its something I really miss in my life. And my crush is definitely not just a "best friend crush" I feel I could be very intimate with this girl. I don't think of her as someone who is the same sex as me, but just someone I find very, very attractive. I feel butterflies in my stomach when I think about her. I do love my husband though. Should I confess my feelings to her just to get it off my chest? I am very sensitive to rejection though, I want her to feel the same way about me that would be enough for me even though we cant be together.
Thanks for reading!!
