Hi Roxannejones,
Welcome to PsychCentral. The woman gave you clear boundaries. I would not initiate any contact with her except for saying "Hi" to her. If you feel like there is no one else to talk to about small groups at church, talk to the pastor privately. Another thing to do is to observe her behavior around other people. It may just be that she has a hard time relating to people. If so, she has a big problem. Reach out to other people at church so you take your focus off her.
