The brief times after church is not enough time to get to know anyone. Friendships require communication way beyond the weather and how the sermon was. I know these things are difficult for you but would you feel comfortable inviting some woman over for a meal and to get to know each other better? Do you see anyone there who looks like they are alone and could use a friend? Or some leader type who could mentor you? And can I ask what type of conversation you tried to have with them that they weren't interested in?
