OK. Do you see why he left you and is still "bonded" with his parents? This is your path to take. Look at your situation like you are looking into a fishbowl. What do you "see" ?
Why would your H be attracted to you in the first place? What did you have that was priceless to him? What have you learned since then that will help you?
To walk down the parallel paths requires you to "lovingly detach." Having no expectations helps with the fear and anger. Love yourself enough to arrive down the path as a stronger, wiser and healthier you. You can handle it.
