There may be a few Mr. Perfects out there, but as a rule I think they want you first for sex, then you must take up where their mommy left off taking care of them and then you are not so sexy when you go from lover to mommy so then they start looking around whether they do anything about it or not and you have to compete with perfected pictures of who they wish you were. Sometimes you become their property, whether they want you or not, you do belong to them so better do as they say. Then there really are a few perfect men on earth that get treated by the wife as most husbands treat wives. He will work a lifetime to give her the moon but she wants the stars too and he can only do so much.
We all expect too much. It should begin and end a partnership, give and take equally.
Tell your wife what you expect and why and vice versa. Might save a lot of marriages before it is too late.
