Can I Erase G-D's Name?!?! #jewish #spouse

so I've always heard that you could erase God's name in order to make peace between you and your spouse but this is what I don't get where does that start where does that stop can I eat like Nan kosher if my wife wants me to eat n kosher the Torah says that you can erase God's name in order to create peace between a husband and a wife which means that God is saying the deepest form of divine Worship Is by making sure there is love and connection and trust between spouses there's peace in the home but that does not mean that a person needs to sell their soul and be inauthentic in order to maintain the peace so for example if my spouse needs me to eat non kosher what is she going to gain by me eating non kosher that's a form of control that's unnecessary for me to impose my desires on the other spouse who may have certain convictions is unfair
