My answer
I think people these days are often too immature going into marriage, expecting too much of the other person without understanding the gravity of how much "give" and understanding is necessary to make it work.
Your partner is a PERSON, with their own feelings, needs and past to deal with, and with hopes and dreams all their own for the future... and that is a huge responsibility to understand this going into the marriage.
I happen to be a bit old fashioned, so I feel that the man should bear extra burden for his family. I feel (and it is OK to disagree) that the man should shoulder the brunt of the responsibility to be "the man" to be the strong one and do more than his share to make sure the family is safe, loved and protected in this world.
I just think the man should do more as the protector of not only the physical aspect of the family, but the emotional one as well. I could not tell you how many times I have stepped in, when needed, to show leadership within my family when my wife and son may have gotten into bickering about something, say my son needing to do his chores or something, and it turns into mom and son being too angry with one another... at that point, I feel it is my responsibility as a father and husband to step up and remind the two of them that they should be loving each other, and respecting each other...
I get them to look into each others eyes and remind them of all the love and great things we've shared and everything that has got us to where we are today... and this usually ends with some self-realizations, teary eyes, some apologies and love once again being the word-of-the-day once again.
Now THAT, to me is what a father should be doing...
Foster, protect and restore love into the family.
