For me, it just came off as them all being somewhat selfish and really insensitive to the MC's feelings. He made it clear to Rebecca that he was(at the time) temporary and he wanted to return home to at least let his family know he wasn't dead in a ditch somewhere. I suppose some blame can be placed on him a bit, but he did say that he'd try to come back. For me it just seems like all the girls really did want him to throw away his old life. If his family doesn't know he's alive? Big deal so long as they're happy then it's all good! The MC wanting to see his family again? Well now, that's just no fair.
