Isolated sister in Christ

Hello my brothers and sisters in Christ. I have a request, please pray that I can be planted and grow in a Bible preaching and teaching Church that is on FIRE for the Lord. I totally feel the Church I’ve been attending in Luke warm and has watered down sermons. I don’t fellowship with any of the people neither. Most folks leave so fast after church, and I don’t see many who I can talk to. They have life groups but I don’t go. My sister invited me to this church but she doesn’t go herself. I listen to sermons from another local church, but 10 years ago I met a guy there who I dated for a long time and we have been broken up for almost three years now. I just don’t know if I should stay where I am or go somewhere else.
