I agree with developing the friendship. I had Jody as a coach. Did she go through the stages with you? Friendship is where I began in my reconnection with my H. It helped a lot. You don't have to gush over it..just treat him like a neighbor. Friendly and polite. It sounds to me like the friendly text is exactly what was needed to break the ice. I know we all do this but don't overthink it too much and take it slow.
