So I was against this for a while but I gotta be honest, it helped mine and FH relationship so much already! He already feels more confident about us getting married and we are both realizing faults in ourselves that we need to work on to build our relationship. If you are on the fence about going, I HIGHLY recommend it! Plus you get money off your marriage license...
If you are in the Atlanta area we went to the marriage prep workshop at Johnson Ferry Baptist Church in Marietta. Wasn't overly religious if your not into religion either!
