He lives across the globe
It might sound cliche but if you love him that's not the problem.
I fell in love with someone from internet and I decided to meet him in real life. We live in different locations on the same continent (He's in the north, I in the south) so it may seem to you that was much easier but it was not. There are always problems with money and with documents needed to enter certain country and everything but you can succeed if you are really determined to do that.
But, I totally forgot to ask you how does he feel about you?
