L.B.
Yours is one of the reasons I left my first church - the one where I accepted Christ and was baptized. It was a difficult decision but I had the same sense of cliques and not fitting in with the other members. I, a single struggling Mom, most of the other women, married and not struggling. Don't get me wrong, they were lovely - I just felt uncomfortable.
So I church shopped....visited several, finally decided on one.
When I moved 3 years ago I did the same thing - my son was old enough to be a part of the decision for we went to bunches of churches. One thing about living in South MS is abundance of Baptist churches to select from. :)
The one I selected is homey, and family style, and everyone hangs out and does things together...sure some families spend more time together - but they have known each other longer.
You need to shop around, find a church that has the atmosphere that you want - they are out there.
Good Luck and God Bless.
