Welcome to PC demilune. Might be helpful to have a mantra when the old thoughts arise ... something like "that was then, this is now, and I am moving on". Life goes forward, you know, and letting go of the past is in your best interest. If you do get stuck, have someone lined up that you can call to process things with in a healthy way (not your boyfriend because it is not his responsibility to 'fix' the old stuff.)
I try not to get too invested in labels as I think they can keep me stuck. You made a wise move, let a bad thing go, and are now creating a new life. Best wishes. It sounds like you are doing just fine.
