My current group:
Me (the DM): Single (have had SO's in the past but prefer meaningless physical relationships for the most part)
Player 1 (Seance): Single (has had SO's in the past).
Player 2 (Firetongue or whichever alt he's on now): In a committed long-term relationship; not married.
Player 3 (Crazy Artist Chick): In a committed long-term relationship but a somewhat open one; has been married (and then divorced) in the past.
Player 4 (Takes Forever to Act Guy): In a long-term relationship with Player 3; not sure how committed HE is.
Player 5 (Golden Boy): Single AFAIK; has been in LTRs before but never married.
Player 6 (Dude Always Plays Fighter Types): Married, no kids. Only marriage; has lasted years at this point and seems very strong.
Player 7 (New Guy; 17 years old): Son of the best friend of Firetongue's girlfriend; cool dude, AFAIK he never leaves the house except to come game with us or work; AFAIK no LTRs, too young to count against him especially given his emotional retreat after the death of his dad a few years back.
