"Yes dear." Learn those words. And admit that as a man, you really do need help rounding off the rough edges. Heck! You probably don't even know you have rough edges. If you married "up" as I have suggested before, you are in for the ride of your life and will, most likely, be a better man for it.
Seriously, pick your battles carefully. There will be differences of opinion on most any conceivable subject. Most battles are not worth winning in the long run. Compromise when necessary. Compromise when it's not necessary.
Verbal abuse sometimes leaves a scar. If an argument is required, and they sometimes are, be a gentleman. Walking away, pouting and withdrawal are not conducive to good communication. I'm not talking about being a wimp, stand up for yourself when necessary but in a manner that doesn't threaten or hurt.
You're a male, probably under the age of 100, and ergo, you are a doofus. Recognize this and you will be a happier man. Your wife knows this and she will, gently over the years if you are lucky, do her best to make you a better man than you are now. It's her job in life now and she probably sees you better than you see yourself.
I recently became a widower and offer this from the bottom of my heart: "Treat her with respect at all times."
Unanticipated gifts are the best. Roses and other gifts are not just for when you mess it up. They are required when you do mess it up though.
So, buckle up, do the best you can, you'll get better at it as time goes on, and enjoy every memorable moment of your new life.
