The person who seems to be unaware of boundaries is the OP, not the group leader. The leader is very clear and it seems from the boundaries drawn that the OP has been making the leader uncomfortable and using the small group as an opportunity to be close to and be in contact with the leader.

I agree the pastor should be brought in, but unfortunately for OP it may end up that OP might not be allowed to attend the group any more if she doesn't respect the leader's boundaries.
