Mel, It sounds like you've had a very busy end of school year. I'm glad you were asked to go full time and have a chance to sub over the summer. Will you be able to back after the summer break full time?
You are very wise to take each day as it comes. Don't make too many plans too far ahead because things can change very quickly and I would hate to see you disappointed or discouraged along the way.
I'm also glad that he's been willing to be transparent w/you. That's a step in the right direction. If you aren't ready to talk about things, then advise him of that. There is no need to rush the process for yourself. You will know when you are ready to deal w/everything.
Enjoy your summer!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
