You love each other. Maybe you should start there? Make it explicit what about the unique personality of the other you love and what strenghts in the unique relationship you've built together you appreciate.
Then use MBTI as a mere tool (not directive or predictive 'Truth') serving this love and this common project. It can provide a nuanced and tolerant descriptive common language. And it can propose perspectives to help mutual understanding, communication and win-win ways of working through conflicts towards constructive and respectful solutions. And learning from other's experiences like you've asked for here can be an inspiration too.
Love first, regardless of type theories and statistics about mate-matches. Then MBTI as a valuable supportive tool for the actual love you've both created, I'd say.
