The internet sure is a global network; bringing people together that we'd never imagine we'd interact with IRL. Some relationships can be good; others not so good.

You have a degree of responsibility entrusted to you by your folks. I think you need to keep your relationship with "G" above board. No hanky panky swapping nudies over the internet or sexting / skyping.

If you're able to maintain a solid friendship and he supports you; great.

But he does need to stop that marriage talk .... that's kinda creepy.
