Someone crash course me in NC right now. My ex and I start tomorrow and I don’t think I’ll ever be ready.

We broke up on good terms so we don’t have any hate nor animosity towards each other. Reasons for breaking up are distance and wrong timing; current lives just don’t align with each other’s right now. We had the perfect relationship, the respect was always present, the love was always fulfilling, and needs were always met.

How do I deal with this knowing it’s what’s best for us right now even if I just want to be with him?
