I think you are asking the wrong questions really.
I am not an advocate for moving distant lovers into ones home without a trial period of living apart. I really have seen very few situations where moving someone in that is barely known by one or both partners triad or Vee has worked out. I see no reason why this would be different. Especially with the impending issues that have come up.
I think he should move near you all and find his own way in your location. Especially if he isn't a fan of being away from where he lives right now. Then he can fit into more of a routine of every day than visits back and forth. You can also establish a relationship with him... something that is essential when someone moves into your house. Who knows, maybe just living in the same area will be plenty for all of you.
