Kinda of a mirror thread to LS's:
Guys, best advice you've ever gotten about this world?
Me:
1) Be careful. Trust your instincts. If it doesn't feel right exit yourself from the situation (even if you are out a little money). There is always tomorrow.
2) Respect the boundaries of the relationship. Don't fall in love with a provider. Also hold her accountable for adhering to the boundaries & cease further contact at the first sign she is unable to do that.
3) If you have a bad date or potential date, even if she was downright mean or tried to rip you off, try not to waste your time or energy getting angry about it. Learn from it, then move on. Almost by definition not all of your dates with meet your expecations. That is part of the game.
