Bright, When something isn't working, it's okay to try something different. You sound like you are now in a different place and his responses aren't bothering you as much. It takes time to detach and you are doing it slowly but surely.
Your h really doesn't want to separate things because he knows that he can rely on you to take care of things. Look at what he's asked for (again) and you provided him the info (again). His memory is mush and it's going to be that way for quite some time.
I'm glad to see he's able to send emails/texts again. Poor man. No, it's not weird at all to have a little bit of fun in trying something new to see if it will work...just keep the expectations low or on zero.
I'm glad you are getting out w/your co-workers.
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.
