Online Relationship ...confused :(?

[solly]

So me and him met through Yahoo chat rooms.
We just chatted carefree for 5-6 months without even knowing our actual names or professions.
Then he moved to US and me in India.
Still we continued chatting and exchanged numbers and talked over phone. Later we came to know each other's names and work details and checked out profile in Facebook.
Its been 1.5 years since then and we still continue chatting and from silly friendship , we have grown feelings for each other.
He has however asked me to come on Skype , but everytime I have been skeptical of my not-so-pretty average looks and found out some reason to avoid .in fear that it may stop our relationship altogether.
I know thats very immature.but i guess people act silly in matters of heat
Should I completely stop chatting with him or come up to Skype and see what it holds for me?
Its the fear of rejection that is stopping me
