<human>: Throwaway because obvious reasons.

Background: Boyfriend, Josh, and Baby Mama, Sarah, are on good terms, don't live together but he sees his son, Michael, often. I've met her and their son, we all get along. So no issues there. Josh and I have been together for a year, for the past 3 months we've been long distance due to a job offer I received.

Onto the problem, the lease for the house that Sarah and Michael live in is ending soon and cannot be renewed so they have to move soon. Unfortunately the only place they can move to is in a completely different state. Josh currently lives in an apartment with 3 other people so there's really no room for them. Neither of them can currently afford to find a place to live together. Plus Sarah's family is all up in that state. My real problem is that my boyfriend is extremely upset about this. He's been a complete mess and I have no idea how to comfort him, especially with us being long distance. I've brought up the idea of him moving up there with them but I guess that's out of the question. He really loves his son.

Could you distill the essence of the text into 1-3 sentences?
