Should I tell my friend about my boyfriend?

Okay, first of all, I happily have a boyfriend, we met on facebook (yeah yeah I know) We really like and met back in February. And we talk a lot. We skype as often as we can, and by the way. He's in the US Navy and really sweet (and cute :3 ). As of now, he's stationed in the middle east. (He gave me an actual location but I just can't remember) He was in Jerusalem the other day and bought me a cross with my birthstone, and had it blessed. (I'm not big on religion, and neither is he, but I love the thought, it's beautiful. Though I'm not all that big on religion I believe these symbols protect from demons which do exist) Anyway... We like eachother and we plan on meeting up in October. And, well... I think I might want to tell a friend about him. The friend I trust the most. The one I first came out to. And NOBODY else can know about this one. I swear, nobody. Not only would my mom definitely kill me, she might try to get him in trouble because he's in his early twenties.

So, should I tell my friend?
