I'm sorry you're going through this. Changes like this are scary and stressful and bring with them quite a few emotions and very easy ways to spiral. My interpretation is that the relationship is over, he said as much. It's likely he backtracked to minimize hurt and make it sound like a temporary break, but its better for you in the long run to see this relationship as over. Half a decade is more than enough time to determine if a relationship will continue to flourish....or if it has run its course.

I wish you all the luck in building space for yourself and grieving the closing of this chapter in your life
