Meet women for friendship in places you would go to pursue your own interests, like a hiking club, an art workshop, a class or church. Women have many of the same daily activities as men, so you can find friends at work, the library, the gym or online.
Business networking groups, support groups, and even singles events can be places for finding female friends.
When you meet someone in a shared public setting, you are likely both there for the same reason. This shared activity gives you something in common, whether it's a common interest or a need. This can be a seed for starting the new friendship.
