Alone in a Crowded Church

My wife and I have a continuing problem of not finding a niche in a church. We don't have kids. We're both homebodies of a sort.

Meeting people is not a huge problem (though it is an obstacle), but what does it take to have other church members take a genuine interest in you? We've always lacked any sort of Christian mentorship or couple-to-couple friendship from church members. (We have some of that from great college friends, but I'm not talking about them.) It does not matter if we are participating in church activities or ministering to others or just warming pews, there just seems to be a lack of personal interest from surrounding people.

Everyone has their own lives. But I wonder how many other people feel as I do. I wonder how many of them I sit next to in church.

I'm capable of skipping church frequently because I know that nobody will miss me when I'm gone and those who would miss me don't go to my church.
