My advice is to listen to the advice that your spouse gives you, I mean the subtle an not so subtle things they tell you means something to them or bothers them and , remember it, use it.
Second, anytime you have a disagreement ( and you will disagree, because you come from two different worlds) remember not to escalate it into a fight. No argument needs to become a fight, but every argument can easily turn into a fight, how? By saying insensitive things. Think first,( the inspiration of my user name) will this bother me in two minutes in two days or two weeks? Is it worth getting argumentive over? Even the most hot topics can be discussed and sometimes argued in a civil way. As long as you don’t say something you’ll regret you’ll make up easily it’s a matter of time.
Last , you can never say a compliment too many times. It’s the glue the binds a happy marriage pour it on. Every day all the time.
