Patience is a gift. Beautiful pic!
There is never anything wrong with slowing down. You need to move at a pace that is comfortable for you. He should be able to understand this and have no problem with it. It's the ones that push ad try to rush things that you have to worry about. Time is on your side. Enjoy the moment, let things develop as they will, and soak it all in. You've waited a long time, so enjoy it!DV
It's all good in taking time to build trust, clear your mind and make things clear. Sending you my best wishes :)
