Lack of communication. My bad.

I am the worst.
My eyes have been opened to how entirely terrible I am at handling dating situations and relationships. I am incapable of discussing my feelings and my intentions with a gentleman of interest. When in the company of my roommates or my mother, I can rant all day about how frustrated I am or about how I feel about someone, but the second the gentleman in question is present, I can not speak of such things. At all. It really is ridiculous.
I'm sure you can deduce that I have yet to speak to The Youngin'. I am unintentionally letting it just fizzle away, which is completely unacceptable. I know I need to speak with him, but I have yet to find the words or the courage or the desire.

And now I have some words that I need to speak to Samwise, but I can not for the life of me say them to his face. I have not mentioned Samwise to you, my dear readers, which is rather unfortunate because he is the dearest, most loyal, surprisingly spontaneous boy that I have ever had the pleasure of meeting. I met him back in May, and we have been incredible friends ever since. I've had a crush on him on and off for the last 4 months. Here's the catch: he has a missionary. A girl who still has nearly a year before she gets home, but he is still in love with her and absolutely wants to marry her when she returns... Yeah, again with the whole, "Friendly Kisser can't ever have a normal dating situation" thing.
Long story short: Samwise and I kissed in July and then NEVER TALKED ABOUT IT (yes,I have a problem), and then everything went back to normal and we were still just friends. It has been as such for months now, but then last week he called me just to talk and invited me to hang out every single day. What?!
Don't call me and be an absolute sweetheart when I already like you but we both know that nothing is ever going to happen between us.
Annoyed.
And this, my friends, is where communication comes into play. It would be so much clearer if I could just ask him what was going on in his mind and if I could verbalize what is going on in mine. And this is where I struggle and things fall apart. How have I never realized how miserable I am at this?! I need some communication skills.
