Well, I can give ya some of advice my father, him and mom made it 62 yrs....somehow LOL.
Second- the honeymoon is over when you get married
Third- wedding cake is birth control
Fourth- for birth control, use the window method. When it gets stiff, go slam it in the window,...this coming from a man with 5 kids
Seriously though, Elfman pretty much hit everything on the head. Women think in a circle with many subjects going at once, men think in a line, one subject at a time. It can be VERY frustrating until you figure it out. I'm almost 19 yrs in and still lost most of the time
Just give her full attention and it does help to sometimes repeat what she said so you are on the same page. And don't try to always fix everything, sometimes they just need to talk, vent, etc.
One of biggest keys to remember I think, is your are one once you get married, each other should be first. This gets very rough when kids come along, they become priority, but always remember to give each other time and do not let your marriage relationship take a back seat to raising the kids. Get a baby sitter, go on dates, etc. My wife and I seem to be closer now since our two are old enough to stay home and take care of themselves, we are able to go do as we please wihout dragging them, makes a big difference....but that's down the road advice.
Express your opinions,thoughts, wants, etc, but do it not in anger, take a breather if needed and come back later.
communicate, communicate, communicate.
