Well, it also depends on how vulnerable you are. If you are playing the "woes me" role, IRL or Online... you're going to get played and lied to. If you put it straight and dont expect pity "Oh all my exes treated me like crap" What emotions do they have to play on? Also, I learned a good way of weeding out the liars and players is to take time. If someone is willing to take it one step at a time, not rush things... they're more likely to be in it for the long haul and tell you the truth!
