In the future you might suggest that you simply watch your kid at home and let her go to the cult meeting by herself. Aaaaaand that's the end of my unsolicited advice.
On to the solicited advice:
When people say "We miss you" I always try to respond with something like "Really? I haven't heard from you - you should come by for a visit and we can have a few drinks." In my mind the goal is to make them as uncomfortable as possible and to force them to realize that they've just lied to you - they don't miss you, they've just been told to tell you that they miss you by countless talks over the years. In most cases, the people telling me that they miss me are folks that I've literally never had a conversation with (in one case it was someone that I've never spoken a word to and know nothing about her beyond her last name). Because these people really don't know me, the suggestion that they come by for drinks tends to make them very uncomfortable.
"Are you going to start coming back?" - My response would just be "No" said in a firm, decisive voice.
"Wasn't that a wonderful meeting?" - "You know, I really can't say that I enjoyed any of it."
I guess your responses would really depend on your goal, though. In my case I don't care if any of them shuns me, and in some ways I'd prefer it. If you're looking to keep some relationships intact then just keep your mouth shut.
