Early in my marriage my wife and I had numerous arguments over halachah.
Me: But [my] Rabbi X [YU guy] says this.
She: But [her] Rabbi Y [Lakewood guy] says not this.
For the sake of shalom bayit I compromised. I agreed to follow her rav on all matters except when he agreed with my rav, and only then would we follow my rav. Something similar might be worth considering here.
