Don’t overlook the influence of pride in your relationship.
Pride fortifies the idea that makes you feel that your partner does not deserve an apology from you, perhaps because of your status or influence in your relationship.
Take charge of your pride and do not let it control you if you really want to take responsibilities for your actions and make amends. It prevents you from adopting simple things which can help resolve simple problems in your home.
I have seen cases where spouses detest being the first to apologize to their other halves over slight arguments because of the fear of being seen as the weak ones.
There are also cases of spouses who refused to apologize for their wrongs to prove that their actions were right, or to play hard-to-get to their partners.
One thing should be clear: Relationship or Marriage is not a game of two people who did clever things individually to win, but a union of two people who did things together as if they were one.
Treat your partner the way you will want anyone to treat you, and you will know exactly what to do when you have issues in your home.
