Question: Is it disrespectful to fully investigate my girlfriend's myspace account? At the same time is it wrong to think "who the eff is this guy?"  I usually don't get jealous, but even I don't have a myspace account and... ugh...

Answer: It's absolutely acceptable.  This is how I found out that the last guy I dated was lying to me and cheating.  MySpace is public domain.  It's not "stalking" or being disrespectful to look into it if it's up for the world to see.
