In order for the ride to stop, Get off the coaster.
I noticed in my situation that the less i knew, the better i was. Live for yourself. Be someone strong, independant and charming. If he doesn't notice you then, maybe someone else will!!!
Hard to believe but time does help. Give yourself a day off from your pain. Very hard to do but possible. If it's to hard to accomplish right now, start with 5 minutes.
Good luck.
