Looking for advice on how to support my partner and calm his worries - we're getting married next year and my fiancé is terrifed he is going to be a bad husband and we'll end up hating eachother because his parents don't have a good relationship at all and he can't shake that we're not going to end up like them (even though we are nothing like them), he's seen plenty of other relationships/marriages that are working well but that doesn't seem to help.
