Your passion for planning will help you focus on arranging the process rather than your emotional strain. This will give you a great opportunity to apply your organizational skills. No one else can create better long-term plans for your relationship, and the distance between you two won’t be an obstacle for you.
There are many things that you will need to discuss. Decide how long you can live apart, whether it’s possible to move together and schedule the time. But don’t forget that in time the circumstances may change and then you will need to reconsider your plans. Try to stay flexible, no matter what.
