Say something like, “Ive reflected and thought about my decision over this past week, and I still feel the same way.” And perhaps meet, but with a clear end time to the interaction so that you both don’t get stuck in a break up talk loop! Be firm in what you want and need; but obviously with compassion, it doesn’t sound like they want to break up so they may resist but ultimately no one should be forcing you into a relo you don’t wanna be in! Hope all goes well x
