For me, it was at the end of the first day we met in person. That felt right. Prior to this we had worked on our spiritual and emotional(?) foundation over the phone etc for 100 days. We talked about anything and everything - the silly, the godly, the mundane, the exciting, the easy and the challenging things, our interests, families, lives in general. We prayed for each other and challenged and encouraged each other. It was all very new and exciting, but saying, "I love you" didn't feel forced or weird, it came naturally.
