I Am In a Long Distance Relationship

I've been with a guy for almost 4 years before and never have I had the feelings like I do now.

I'm on my 11th month of dating this guy and for some reason I get really nervous and also scared around him. I feel myself becoming girly. It's like my heart is trying to tell me he's the one I want to spend the rest of my life with..but once again I've never felt this way before.
Hell I use to feel like love wasn't meant for me..
I'm scared because everyday these feelings get stronger... I don't plan on rushing things...if he is the one I'm meant to be with then that'll be great...if he isn't then at least I met an amazing man in my lifetime....
I just wish I could control these feelings..
