You have a similar situation with mb28, but in your H's case I get the feeling he doens't WANT to be married and haev the responsabilities of a family and a spouse
I think mb28's husband WANTS a wife and a family... he just doenst realise he already HAS that .. or he feel so miserable he doesn't have any hope that he can repair it
again its mr mb28's MOOD holding him back... all the hope in the world is there... he is just too miserable to see any of it
Your H hasn't fully grown up yet I don't think.. in the sense of accepting responsabilities... mb28's husband wants it, he just has from his perspective two equally conflicting choices...
The film Beautiful Girls covers three stories of three men who make a mess of their relationships and refuse to grow up... it expresses this dilemna quite poetically...
