How I read his text wasn’t him being scared off at all. I took it as, “I’m giving you the space you need to heal, but want to let you know I am here and thinking of you.” Because if he were scared, he most likely would not have reached out following you telling him you needed space. It seems he wants to keep the connection open.

If you are in a place emotionally to reconnect, send a message or call him letting him know how you are doing and thanking him for reaching out. That you appreciate his support.
