Oh my!

I've done it again! I am completely twitterpatted with a certain young man......and I really must refrain. Sure his sister tells me that he likes me, she and I are good friends, but I shouldn't be this infatuated with him. It's just not healthy. Especially because he won't be an RM for another two-ish years!!!! GAH!!!!! And I love his family! They have adopted me into their family, since I am currently away from my own, and they invited me to do things with the family! So I'm bound to run into him. I am trying with all heart to just be friends with him, but I always tend to slip up on it and flirt away, then I realize what I did and close myself up again. I've most likely confused him so much! Do any of you have suggestions for me, to help me or rather help the boy, to preserve his sanity!?!?!????
