I would continue as you have been and I wouldn't bring up relationship talk to her. If she initiates the relationship conversation, you can respond...but no expectations. The less you pursue her, the better.

BTW, please start a new thread.

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.
