I wouldn't turn down rides unless you have a back up plan w/someone. You never know when your back up plan might have an emergency and it's good to keep things civil and open just in case you do need his assistance in the ride department. I would look upon him as a distant friend and only call him if you absolutely have to for assistance (last resort).

Please take care of yourself.

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.
