I went to the same church as my ex's best friend's family. They were really nice to me and asked me to sit with them and go to lunch. But I was so uncomfortable. It just reminds me of him.
I kept telling myself over and over what my Mom used to say, "You go to Church for God, not the people".
I quit going. I know, thats horrible. I could go back to my old church but I want to find one closer.
There is no way I could go to the same church as my ex. I don't know how you even got through that. But it is what you want. If you want to find another church, go for it.
I haven't met any singles at mine.
