Imvu relationships are a nice thing to have when you need someone to talk to BUT, i would never fully commit into a imvu relationship as in introducing her to irl friends or paying her rent or something like that (yes my Ex-girlfriend once asked me if i could transfer her 200$ for rent).
I know alot of people that flew their E-partner to them so could meet but the distance will never really be conquered which is just the biggest factor for a healthy relationship (after trust).
