How To Make a Guy You Haven't Seen in 10 Years Like You Again?

I also haven't had face to face contact with him since high school.

But I want to get his attention. Should I message him on Facebook? Send a bikini pic?

How do I get him to like me again? This is a guy I rejected a decade ago, he lost interest, and now I changed my mind/realized how sweet of a guy he is
Update: I just want him to love me like he loved me before. I'm afraid I won't ever get that level of adoration from a cute guy ever again. I'm not 14 and pretty and skinny anymore. I'm now a chubby 23 year old with wrinkles and acne scars:(
Update 2: How is the joke on me????
