To be honest, I don't worry about it. God decides these things, like whether we're a match or not. It's just enough of a pleasure for me to be socializing with a new person, whether it works out or not. If it's not a match decided by God, there is nothing that the woman and I could do to change that. If it is a match decided by God, no amount of mistakes we'd make could take that away. So, there is never a true reason to worry. We could always just enjoy ourselves and relax on a date.
Godspeed.
