The first date should not take place in private, but also without friends and family members. Consider meeting only in relatively crowded places, don’t agree to a home visit and don’t invite a girl to your place. If a woman is persistent in inviting friends, find a reason to refuse gently or offer your option.
You should also not invite friends to the first meeting, even if the girl proposes to get four together, taking her bestie with her. In such a company, you cannot be alone and have a heart-to-heart talk. There is also a chance that a woman will like your friend more.
