I think your over reacting here... I've played a few of these "online games" and the chicks (if they ARE chicks) tend to be very.... i dunno what the word is. But they use "hun" "honey" "baby" "babe" "sweety" all the time.
As for the "added her as a real friend" thing? Do you mean myspace or facebook? Because that's not much different then the game.
Personally i wouldn't let it bother you until he starts meeting with them in real life. That's a bit much.
"We are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.
That’s kinda cool! That makes me smile and I actually feel quite large at the end of that.
It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us."
