Honestly, you don't have kids together so you don't have to worry about them knowing you pushed it through.
If it can help you move on then I would go for it.
I vacillate between just having it out with him... getting everything off my chest instead of stuffing it down and being done. To trying to reach a place where it emotionally doesn't effect me. To explore what a cooling off period is like - for me? for him? What if we were too hasty? What if it didn't have to come to D?
I think I need to let it sit and at the same time find a way to go about my life not looking over my shoulder.
