when the one you gave your heart to....

I'm in love with the most wonderful man it the whole world, it's rather complicated but he works for my parents and he's 21 and I'm 17 (18 in October) I was writing on my blog about how much I love him but I didn't use any names but I guess I was to specific and he and my co-workers found out who I was talking about. I stopped posting blogs that night and never spoke to my love about the incident. From the time I meet him things just went really wrong. I sent him messages that were just talking and trying to make friends with him and he didn't reply to them. My 12-year-old sister kept making me look bad by chasing me around and really bringing me down to her level. When I would try to stop her from telling him embracing things about me it only was more embracing because it look really dumb by fighting and doing things to physically hold her back from him it was really really bad. Then the night I found out that he knew I liked him I got a little tipsy and made a real fool out of my self. As you can see it was just not good I just love him soo much I just want to be his friend at this point. He's moving to Boston to go to school and he quit his job. What can I do to try to make friends with him? Please help me I can give more details then it really complicated
